implement the needed find-file hook. It can't be that hard.

and involve encoding/decoding e.g. crypto or compression. It was a
mistake to have image display functions in format-alist and I don't

A-men. I still remember the pain it was to edit an XPM file while
those functions were there.
C-x C-f foo.xpm RET -- the image gets displayed in the buffer
C-x C-i foo.xpm RET -- the image gets inserted in the buffer
