Images with relative paths won't show

He!

I've installed FCKeditor on an existing site. The problem is that all images have relative paths like 'pics/mypic.jpg' (without trailing '/') and won't show up in the editor window (I see the placeholder for broken links). When checking the Apache Error Log I see that the browser is looking at 'http://www.myserver.com/fckeditor/editor/pics/mypic.jpg' instead of 'http://www.myserver.com/pics/mypic.jpg'. Adding a trailing '/' to all image-urls would do the trick but i don't want to do this because my project should not need to reside at the server-root.
I'm using a custom image- and link-browser.
So, if anyone knows how to fix this (or how to code a workaround) please help me.

Thanks, Bobo
