Get Timthumb to work in WordPress Multisite


There are some problems with the timthumb.php script with Wordpress multisites. A lot of themes are using the timthumb script but the script isn’t working perfectly with the multisite setup because there is a problem with the domain / files location. By using a modified version of the Timthumb script you can solve these problems.

Update 2019: TimThumb is no longer supported or maintained.
