FCKEditor - broken images in editor

Not sure if this is the correct forum, but wasn't sure where to put it.

This is a question for anyone with experience using fckeditor.

I've tried looking in their forums, but with no luck, so guess I hope someone here has experienced the same problem as me.

I pretty simple. Currently when I add/upload images to the editor with the build in upload function, url to the images turns out like this:

userfiles/image/bik.jpg - which is relative to the root document. But since i've integrated the editor in a CMS a few parent directories behind, obviously the path to the images turn out wrong.

So my question is, how do I make the url path absolute,- so it would turn up like: http://www.mydomain.com/admin/parent.../image/bik.jpg
