Better would be to save the major mode, and then switch to
"saved-major-mode + image-minor-mode". No need to modify anybody's
keymap. And I think that image-minor-mode should only be used while
displaying text: basically, image-toggle-display should toggle between
image-mode and the other major-mode (complemented with
image-minor-mode).
That would be cleaner,
