+ GNU GENERAL PUBLIC LICENSE

+ Version 2, June 1991

+

+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
5
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
6
+ Everyone is permitted to copy and distribute verbatim copies
7
+ of this license document, but changing it is not allowed.
8
+
9
+ Preamble
10
+
11
+ The licenses for most software are designed to take away your
12
+ freedom to share and change it. By contrast, the GNU General Public
13
+ License is intended to guarantee your freedom to share and change free
14
+ software--to make sure the software is free for all its users. This
15
+ General Public License applies to most of the Free Software
16
+ Foundation's software and to any other program whose authors commit to
17
+ using it. (Some other Free Software Foundation software is covered by
18
+ the GNU Lesser General Public License instead.) You can apply it to
19
+ your programs, too.
20
+
21
+ When we speak of free software, we are referring to freedom, not
22
+ price. Our General Public Licenses are designed to make sure that you
23
+ have the freedom to distribute copies of free software (and charge for
24
+ this service if you wish), that you receive source code or can get it
25
+ if you want it, that you can change the software or use pieces of it
26
+ in new free programs; and that you know you can do these things.
27
+
28
+ To protect your rights, we need to make restrictions that forbid
29
+ anyone to deny you these rights or to ask you to surrender the rights.
30
+ These restrictions translate to certain responsibilities for you if you
31
+ distribute copies of the software, or if you modify it.
32
+
33
+ For example, if you distribute copies of such a program, whether
34
+ gratis or for a fee, you must give the recipients all the rights that
35
+ you have. You must make sure that they, too, receive or can get the
36
+ source code. And you must show them these terms so they know their
37
+ rights.
38
+
39
+ We protect your rights with two steps: (1) copyright the software, and
40
+ (2) offer you this license which gives you legal permission to copy,
41
+ distribute and/or modify the software.
42
+
43
+ Also, for each author's protection and ours, we want to make certain
44
+ that everyone understands that there is no warranty for this free
45
+ software. If the software is modified by someone else and passed on, we
46
+ want its recipients to know that what they have is not the original, so
47
+ that any problems introduced by others will not reflect on the original
48
+ authors' reputations.
49
+
50
+ Finally, any free program is threatened constantly by software
51
+ patents. We wish to avoid the danger that redistributors of a free
52
+ program will individually obtain patent licenses, in effect making the
53
+ program proprietary. To prevent this, we have made it clear that any
54
+ patent must be licensed for everyone's free use or not licensed at all.
55
+
56
+ The precise terms and conditions for copying, distribution and
57
+ modification follow.
58
+
59
+ GNU GENERAL PUBLIC LICENSE
60
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
61
+
62
+ 0. This License applies to any program or other work which contains
63
+ a notice placed by the copyright holder saying it may be distributed
64
+ under the terms of this General Public License. The "Program", below,
65
+ refers to any such program or work, and a "work based on the Program"
66
+ means either the Program or any derivative work under copyright law:
67
+ that is to say, a work containing the Program or a portion of it,
68
+ either verbatim or with modifications and/or translated into another
69
+ language. (Hereinafter, translation is included without limitation in
70
+ the term "modification".) Each licensee is addressed as "you".
71
+
72
+ Activities other than copying, distribution and modification are not
73
+ covered by this License; they are outside its scope. The act of
74
+ running the Program is not restricted, and the output from the Program
75
+ is covered only if its contents constitute a work based on the
76
+ Program (independent of having been made by running the Program).
77
+ Whether that is true depends on what the Program does.
78
+
79
+ 1. You may copy and distribute verbatim copies of the Program's
80
+ source code as you receive it, in any medium, provided that you
81
+ conspicuously and appropriately publish on each copy an appropriate
82
+ copyright notice and disclaimer of warranty; keep intact all the
83
+ notices that refer to this License and to the absence of any warranty;
84
+ and give any other recipients of the Program a copy of this License
85
+ along with the Program.
86
+
87
+ You may charge a fee for the physical act of transferring a copy, and
88
+ you may at your option offer warranty protection in exchange for a fee.
89
+
90
+ 2. You may modify your copy or copies of the Program or any portion
91
+ of it, thus forming a work based on the Program, and copy and
92
+ distribute such modifications or work under the terms of Section 1
93
+ above, provided that you also meet all of these conditions:
94
+
95
+ a) You must cause the modified files to carry prominent notices
96
+ stating that you changed the files and the date of any change.
97
+
98
+ b) You must cause any work that you distribute or publish, that in
99
+ whole or in part contains or is derived from the Program or any
100
+ part thereof, to be licensed as a whole at no charge to all third
101
+ parties under the terms of this License.
102
+
103
+ c) If the modified program normally reads commands interactively
104
+ when run, you must cause it, when started running for such
105
+ interactive use in the most ordinary way, to print or display an
106
+ announcement including an appropriate copyright notice and a
107
+ notice that there is no warranty (or else, saying that you provide
108
+ a warranty) and that users may redistribute the program under
109
+ these conditions, and telling the user how to view a copy of this
110
+ License. (Exception: if the Program itself is interactive but
111
+ does not normally print such an announcement, your work based on
112
+ the Program is not required to print an announcement.)
113
+
114
+ These requirements apply to the modified work as a whole. If
115
+ identifiable sections of that work are not derived from the Program,
116
+ and can be reasonably considered independent and separate works in
117
+ themselves, then this License, and its terms, do not apply to those
118
+ sections when you distribute them as separate works. But when you
119
+ distribute the same sections as part of a whole which is a work based
120
+ on the Program, the distribution of the whole must be on the terms of
121
+ this License, whose permissions for other licensees extend to the
122
+ entire whole, and thus to each and every part regardless of who wrote it.
123
+
124
+ Thus, it is not the intent of this section to claim rights or contest
125
+ your rights to work written entirely by you; rather, the intent is to
126
+ exercise the right to control the distribution of derivative or
127
+ collective works based on the Program.
128
+
129
+ In addition, mere aggregation of another work not based on the Program
130
+ with the Program (or with a work based on the Program) on a volume of
131
+ a storage or distribution medium does not bring the other work under
132
+ the scope of this License.
133
+
134
+ 3. You may copy and distribute the Program (or a work based on it,
135
+ under Section 2) in object code or executable form under the terms of
136
+ Sections 1 and 2 above provided that you also do one of the following:
137
+
138
+ a) Accompany it with the complete corresponding machine-readable
139
+ source code, which must be distributed under the terms of Sections
140
+ 1 and 2 above on a medium customarily used for software interchange; or,
141
+
142
+ b) Accompany it with a written offer, valid for at least three
143
+ years, to give any third party, for a charge no more than your
144
+ cost of physically performing source distribution, a complete
145
+ machine-readable copy of the corresponding source code, to be
146
+ distributed under the terms of Sections 1 and 2 above on a medium
147
+ customarily used for software interchange; or,
148
+
149
+ c) Accompany it with the information you received as to the offer
150
+ to distribute corresponding source code. (This alternative is
151
+ allowed only for noncommercial distribution and only if you
152
+ received the program in object code or executable form with such
153
+ an offer, in accord with Subsection b above.)
154
+
155
+ The source code for a work means the preferred form of the work for
156
+ making modifications to it. For an executable work, complete source
157
+ code means all the source code for all modules it contains, plus any
158
+ associated interface definition files, plus the scripts used to
159
+ control compilation and installation of the executable. However, as a
160
+ special exception, the source code distributed need not include
161
+ anything that is normally distributed (in either source or binary
162
+ form) with the major components (compiler, kernel, and so on) of the
163
+ operating system on which the executable runs, unless that component
164
+ itself accompanies the executable.
165
+
166
+ If distribution of executable or object code is made by offering
167
+ access to copy from a designated place, then offering equivalent
168
+ access to copy the source code from the same place counts as
169
+ distribution of the source code, even though third parties are not
170
+ compelled to copy the source along with the object code.
171
+
172
+ 4. You may not copy, modify, sublicense, or distribute the Program
173
+ except as expressly provided under this License. Any attempt
174
+ otherwise to copy, modify, sublicense or distribute the Program is
175
+ void, and will automatically terminate your rights under this License.
176
+ However, parties who have received copies, or rights, from you under
177
+ this License will not have their licenses terminated so long as such
178
+ parties remain in full compliance.
179
+
180
+ 5. You are not required to accept this License, since you have not
181
+ signed it. However, nothing else grants you permission to modify or
182
+ distribute the Program or its derivative works. These actions are
183
+ prohibited by law if you do not accept this License. Therefore, by
184
+ modifying or distributing the Program (or any work based on the
185
+ Program), you indicate your acceptance of this License to do so, and
186
+ all its terms and conditions for copying, distributing or modifying
187
+ the Program or works based on it.
188
+
189
+ 6. Each time you redistribute the Program (or any work based on the
190
+ Program), the recipient automatically receives a license from the
191
+ original licensor to copy, distribute or modify the Program subject to
192
+ these terms and conditions. You may not impose any further
193
+ restrictions on the recipients' exercise of the rights granted herein.
194
+ You are not responsible for enforcing compliance by third parties to
195
+ this License.
196
+
197
+ 7. If, as a consequence of a court judgment or allegation of patent
198
+ infringement or for any other reason (not limited to patent issues),
199
+ conditions are imposed on you (whether by court order, agreement or
200
+ otherwise) that contradict the conditions of this License, they do not
201
+ excuse you from the conditions of this License. If you cannot
202
+ distribute so as to satisfy simultaneously your obligations under this
203
+ License and any other pertinent obligations, then as a consequence you
204
+ may not distribute the Program at all. For example, if a patent
205
+ license would not permit royalty-free redistribution of the Program by
206
+ all those who receive copies directly or indirectly through you, then
207
+ the only way you could satisfy both it and this License would be to
208
+ refrain entirely from distribution of the Program.
209
+
210
+ If any portion of this section is held invalid or unenforceable under
211
+ any particular circumstance, the balance of the section is intended to
212
+ apply and the section as a whole is intended to apply in other
213
+ circumstances.
214
+
215
+ It is not the purpose of this section to induce you to infringe any
216
+ patents or other property right claims or to contest validity of any
217
+ such claims; this section has the sole purpose of protecting the
218
+ integrity of the free software distribution system, which is
219
+ implemented by public license practices. Many people have made
220
+ generous contributions to the wide range of software distributed
221
+ through that system in reliance on consistent application of that
222
+ system; it is up to the author/donor to decide if he or she is willing
223
+ to distribute software through any other system and a licensee cannot
224
+ impose that choice.
225
+
226
+ This section is intended to make thoroughly clear what is believed to
227
+ be a consequence of the rest of this License.
228
+
229
+ 8. If the distribution and/or use of the Program is restricted in
230
+ certain countries either by patents or by copyrighted interfaces, the
231
+ original copyright holder who places the Program under this License
232
+ may add an explicit geographical distribution limitation excluding
233
+ those countries, so that distribution is permitted only in or among
234
+ countries not thus excluded. In such case, this License incorporates
235
+ the limitation as if written in the body of this License.
236
+
237
+ 9. The Free Software Foundation may publish revised and/or new versions
238
+ of the General Public License from time to time. Such new versions will
239
+ be similar in spirit to the present version, but may differ in detail to
240
+ address new problems or concerns.
241
+
242
+ Each version is given a distinguishing version number. If the Program
243
+ specifies a version number of this License which applies to it and "any
244
+ later version", you have the option of following the terms and conditions
245
+ either of that version or of any later version published by the Free
246
+ Software Foundation. If the Program does not specify a version number of
247
+ this License, you may choose any version ever published by the Free Software
248
+ Foundation.
249
+
250
+ 10. If you wish to incorporate parts of the Program into other free
251
+ programs whose distribution conditions are different, write to the author
252
+ to ask for permission. For software which is copyrighted by the Free
253
+ Software Foundation, write to the Free Software Foundation; we sometimes
254
+ make exceptions for this. Our decision will be guided by the two goals
255
+ of preserving the free status of all derivatives of our free software and
256
+ of promoting the sharing and reuse of software generally.
257
+
258
+ NO WARRANTY
259
+
260
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261
+ FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
262
+ OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263
+ PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264
+ OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265
+ MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
266
+ TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
267
+ PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268
+ REPAIR OR CORRECTION.
269
+
270
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272
+ REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273
+ INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274
+ OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
275
+ TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
276
+ YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
277
+ PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
278
+ POSSIBILITY OF SUCH DAMAGES.
279
+
280
+ END OF TERMS AND CONDITIONS
281
+
282
+ How to Apply These Terms to Your New Programs
283
+
284
+ If you develop a new program, and you want it to be of the greatest
285
+ possible use to the public, the best way to achieve this is to make it
286
+ free software which everyone can redistribute and change under these terms.
287
+
288
+ To do so, attach the following notices to the program. It is safest
289
+ to attach them to the start of each source file to most effectively
290
+ convey the exclusion of warranty; and each file should have at least
291
+ the "copyright" line and a pointer to where the full notice is found.
292
+
293
+ <one line to give the program's name and a brief idea of what it does.>
294
+ Copyright (C) <year> <name of author>
295
+
296
+ This program is free software; you can redistribute it and/or modify
297
+ it under the terms of the GNU General Public License as published by
298
+ the Free Software Foundation; either version 2 of the License, or
299
+ (at your option) any later version.
300
+
301
+ This program is distributed in the hope that it will be useful,
302
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
303
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
304
+ GNU General Public License for more details.
305
+
306
+ You should have received a copy of the GNU General Public License along
307
+ with this program; if not, write to the Free Software Foundation, Inc.,
308
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
309
+
310
+ Also add information on how to contact you by electronic and paper mail.
311
+
312
+ If the program is interactive, make it output a short notice like this
313
+ when it starts in an interactive mode:
314
+
315
+ Gnomovision version 69, Copyright (C) year name of author
316
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
317
+ This is free software, and you are welcome to redistribute it
318
+ under certain conditions; type `show c' for details.
319
+
320
+ The hypothetical commands `show w' and `show c' should show the appropriate
321
+ parts of the General Public License. Of course, the commands you use may
322
+ be called something other than `show w' and `show c'; they could even be
323
+ mouse-clicks or menu items--whatever suits your program.
324
+
325
+ You should also get your employer (if you work as a programmer) or your
326
+ school, if any, to sign a "copyright disclaimer" for the program, if
327
+ necessary. Here is a sample; alter the names:
328
+
329
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
330
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

335
+ This General Public License does not permit incorporating your program into
336
+ proprietary programs. If your program is a subroutine library, you may
337
+ consider it more useful to permit linking proprietary applications with the
338
+ library. If this is what you want to do, use the GNU Lesser General
339
+ Public License instead of this License.

98
  * Make sure that jQuery is only being included once
99
  * Make sure that the Bootstrap javascript file is being included after jQuery
100
+ * NB: This often means putting it after `wp_head()` in your theme's `header.php` file
101
  * Make sure that both jQuery and Bootstrap are being included in the theme header, not footer
102
  * Make sure that the Bootstrap javascript file is referenced _after_ the jQuery file.

  = Can I insert the carousel into a WordPress template instead of a page? =
109
 
110
  Absolutely - you just need to use the [do_shortcode](http://codex.wordpress.org/Function_Reference/do_shortcode) WordPress function. For example:
111
+
112
+ `
113
+ echo do_shortcode('[image-carousel]');
114
+ `
115
 
116
  = I get grey bars at the side of my images / The image isn't aligned (or doesn't reach the far side of the carousel) =
117
 
127
 
128
  = Can I customise the way it looks / works? =
129
 
130
+ The carousel shortcode has a number of attributes that you can use to customise the output. These are described on the main plugin [Description](http://wordpress.org/plugins/cpt-bootstrap-carousel/installation/) page.
131
 
132
  = Help! Nothing is showing up at all =
133
 
134
  1. Is the plugin installed and activated?
135
+ 2. Have you added any items in the `Carousel` post type?
136
+ 3. Have you placed the `[image-carousel]` shortcode in your page?
137
 
138
  Try writing the shortcode using the 'Text' editor instead of the 'Visual' editor, as the visual editor can sometimes add extra unwanted markup.
