The problem with 4, as I see it, is that the user may not notice the
file is in image-minor-mode.  Typing C-c C-c could then lead to
unexpected behavior.

I think, if we go with autodetection at all, it is better to ask the
user in the event of any confusion, rather than using
image-minor-mode.

Of course, if we scrap image autodetection, there is no problem at all
(in the sense that we don't *expect* Emacs to handle this case).
