Thanks. I have successfully made a lobotomized version I called OverwritingStorage that extends FileStorage and overrides get_available_name, _save and delete (and offers a hashed_path classmethod to be used in upload_to callables)
http://djangosnippets.org/snippets/2044/ Now my problem is not being able to wrap my head around computing an ImageField based on another ImageField (in my case, a default thumbnail that can be edited later) But that deserves its own thread.
