There is a little inconsistency: the default values for some formats
are added to `inhibit-first-line-modes-regexps' in files.el.
But other values are added to `inhibit-first-line-modes-suffixes'
dynamically by `jka-compr-install' in jka-cmpr-hook.el.
But this is not important because some image formats are
already present in files.el in `auto-mode-alist'.

Yes, displaying a message is better even when "Malformed mode-line"
is momentarily replaced with "Type C-c C-c to view the image as text",
because it still allows visiting image files.
