Let me add that the requirement that `image-dired' needs Imagemagick
installed should also be documented in the manual (it is currently
mentioned only in the image-dired.el Commentary AFAICT.  The Emacs manual
should provide a complete recipe for users to provide Emacs with image
support.

But again, #4 is really the way to go.  Just documenting how a user
could make Emacs usable is no real substitute for making it usable out
of the box.
