XEmacsen since 21.2.something don't auto-decode images. There are
reasons, I can't remember what they are, but there are reasons.
The variable format-alist is consulted by format-decode which is
call by insert-file-contents-internal, which is too low level for
such a high level operation like displaying an image. If we want to
display images visited with find-file, a find-file-hook should be
used or perhaps something on interpreter-mode-alist. format-alist
should be reserved for things that really are low-level 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 think those
functions should ever be put back there.
