72
+ -------====Website Screenshots configuration - BETA====-------
73
+
74
+ If you just want image thumbnails and don't want website screenshots, you can safely leave this as is.
75
+
76
+ If you would like to get website screenshots set up, you will need root access to your own server.
77
+
78
+ Enable ALLOW_ALL_EXTERNAL_SITES so you can fetch any external web page. This is more secure now that we're using a non-web folder for cache.
79
+ Enable BLOCK_EXTERNAL_LEECHERS so that your site doesn't generate thumbnails for the whole Internet.
80
+
81
+ Instructions to get website screenshots enabled on Ubuntu Linux:
82
+
83
+ 1. Install Xvfb with the following command: sudo apt-get install subversion libqt4-webkit libqt4-dev g++ xvfb
84
+ 2. Go to a directory where you can download some code
85
+ 3. Check-out the latest version of CutyCapt with the following command: svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
86
+ 4. Compile CutyCapt by doing: cd cutycapt/CutyCapt
87
+ 5. qmake
88
+ 6. make
89
+ 7. cp CutyCapt /usr/local/bin/
90
+ 8. Test it by running: xvfb-run --server-args="-screen 0, 1024x768x24" CutyCapt --url="http://markmaunder.com/" --out=test.png
91
+ 9. If you get a file called test.png with something in it, it probably worked. Now test the script by accessing it as follows:
92
+ 10. http://yoursite.com/path/to/timthumb.php?src=http://markmaunder.com/&webshot=1
93
+
94
+ Notes on performance:
95
+ The first time a webshot loads, it will take a few seconds.
96
+ From then on it uses the regular timthumb caching mechanism with the configurable options above
97
+ and loading will be very fast.
98
+
99
+ --ADVANCED USERS ONLY--
100
+ If you'd like a slight speedup (about 25%) and you know Linux, you can run the following command which will keep Xvfb running in the background.
101
+ nohup Xvfb :100 -ac -nolisten tcp -screen 0, 1024x768x24 > /dev/null 2>&1 &
102
+ Then set WEBSHOT_XVFB_RUNNING = true below. This will save your server having to fire off a new Xvfb server and shut it down every time a new shot is generated.
103
+ You will need to take responsibility for keeping Xvfb running in case it crashes. (It seems pretty stable)
104
+ You will also need to take responsibility for server security if you're running Xvfb as root.
105
+
106
+
