- -------====Website Screenshots configuration - BETA====-------
79
-
80
- If you just want image thumbnails and don't want website screenshots, you can safely leave this as is.
81
-
82
- If you would like to get website screenshots set up, you will need root access to your own server.
83
-
84
- 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.
85
- Enable BLOCK_EXTERNAL_LEECHERS so that your site doesn't generate thumbnails for the whole Internet.
86
-
87
- Instructions to get website screenshots enabled on Ubuntu Linux:
88
-
89
- 1. Install Xvfb with the following command: sudo apt-get install subversion libqt4-webkit libqt4-dev g++ xvfb
90
- 2. Go to a directory where you can download some code
91
- 3. Check-out the latest version of CutyCapt with the following command: svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
92
- 4. Compile CutyCapt by doing: cd cutycapt/CutyCapt
93
- 5. qmake
94
- 6. make
95
- 7. cp CutyCapt /usr/local/bin/
96
- 8. Test it by running: xvfb-run --server-args="-screen 0, 1024x768x24" CutyCapt --url="http://markmaunder.com/" --out=test.png
97
- 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:
98
- 10. http://yoursite.com/path/to/timthumb.php?src=http://markmaunder.com/&webshot=1
99
-
100
- Notes on performance:
101
- The first time a webshot loads, it will take a few seconds.
102
- From then on it uses the regular timthumb caching mechanism with the configurable options above
103
- and loading will be very fast.
104
-
105
- --ADVANCED USERS ONLY--
106
- 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.
107
- nohup Xvfb :100 -ac -nolisten tcp -screen 0, 1024x768x24 > /dev/null 2>&1 &
108
- 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.
109
- You will need to take responsibility for keeping Xvfb running in case it crashes. (It seems pretty stable)
110
- You will also need to take responsibility for server security if you're running Xvfb as root.
