image node should have a way to tell user what image file is used for that node and this should be preserved in case the file link is broken (if the file is deleted or removed) until new file is loaded.

Reason: after loading old files and having some image nodes empty, its impossible to find out what image goes to the node (unles user remebers that). Also it would make sharing files with other people more convenient.
