I think we should have a special `image-edit-mode' to support this.  We
could have a keybinding to go to between that mode and `image-mode' (say
`C-x C-q').

In the short-term, I think `image-mode' should stop pretending it can
edit images by making `image-save' into an obsolete alias for
`write-file'.
