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