Changing image path to work with mambo ?

I can't seem to find an easy explanation on how to change to path of which images and flash files are uploaded.
Because I use mambo, the current upload path would be something like root/images/stories/ etc

It took a while, but I got this to work with fck, the only thing is. Fck makes another image and/or flash folder inside my own. This prevents me from using files uploaded with mambo.

So how do I change Fck in such a way it doens't make any new upload folders, but uploads all files directly in the path used for uploads?
