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.
