If you are working through a slow X connection, accidentally visiting
an image file could be a very expensive mistake. In the past,
displaying an image that was overtall could really confuse Emacs.
This has become much better recently, but I don't know how the
situation is with overwide images.
Anyway, there are ASCII-based image file formats like ASCII PBM, PGM,
PPM, PAM and XBM and XPM. Much more often than not, when I open such
files with Emacs, I really don't want to see the picture, but the
source text (to see comments, assignment of colors and palette, ranges
and so on). And using find-file-literally (even if we provided it in
the menus, where it currently isn't) does not cater overly gracefully
for the line endings in those files.

I don't know how well auto-compression-mode deals with things like
missing compression commands. If it fails gracefully, enabling it by
default should not do much harm.
