host/domain added to image path after submit

at first: frederico, what a terrific piece of code! thanks for releasing it into the free software community!

my question: when I use the image upload to upload a file to my web server and switch into the editors source code view, everything looks fine and image links are display with an absolute path (/userimages/myfile.gif) but without a host/domain in front.

now, after i submit the form somehow the host/domain is mangled into all image paths and i get http://www.mydomain.com/userimages/myfile.gif

is there a way to prevent this? often i use the fckeditor locally but want be able to sync the database to a live server which does not work if local host names are in the image paths.

any help? is it the fckeditor which adds the hostname?

thanks,
rincey
