Installation
-------------------------------------
1. Clone from github: git://github.com/mosbth/cimage.git
2. Make the cache directory writable by the webserver.
<blockquote>
chmod 777 cache
</blockquote>
3. Point your browser to `test.php`.
4. Advanced usage. Put `img.php` in your `/img`-directory. Create a `.htaccess` in your
web root folder containing the following line:
<blockquote>
RewriteEngine on
RewriteRule ^image/(.*)$ img/img.php?src=$1 [QSA,NC,L]
</blockquote>
Now you can access and resize your images through `/image/someimage.jpg?w=80`. Very handy.
