problem with embedded phorum and clean URLs

Hi Everybody,

I have a problem with the way the clean URLS are working and a module I have set up in an embedded forum script (Phorum) i'm using.

The problem I have is that the phorum which is successfully embedded into drupal, is giving the URL of images placed in the forum via BBcode to a script in order to automatically resize them. That way they won't mess up the design. This works and looks good in the embedded phorum.

However it only works when the clean URLs are turned off. When turned on (which I choose from the start and need by now) that resizing function does not work.

I did some debugging and got some great help from the Phorum people and we found out that the way the URLs are rewritten is the problem.
Whenever the URLs of an image are passed on to the script for resizing them the URL is "cleaned up" in a way that the script of the phorum is not able to read it and returns a broken image.

Can any of you help me fix this or point me into the right direction.

My drupal rewriting rules are below. They work fine with the drupal and the rest of the page however this particular module for phorum is not able anymore to receive the URL the way it needs it because for some reason it is cleaned up as well.

Help is much appreciated.

Tino
