Relative path vs full path for images and PDF links

[Connie]

Does anyone know where CKEDITOR gets the URL path info from? I had a look at the IMAGE plugin for CKEDITOR but I don't really know javascript that well but it may be in there somewhere.

There are some links to that option for CKEDitor here in the forum insome posts, but I was not successfull to get it done

if you find some helpful info at ckeditor.net, please post it here
the forum there is nearly apathic, that's why I got no answer there once
