Re: Image mode

[Richard Stallman]

    - One function in magic-mode-alist autodetects image types that do not
      make sense to edit (jpgs, pngs, etc).  If the result is ambiguous
      (as determined by checking auto-mode-alist), prompt the user about
      whether to use image-mode or the non-image mode specified by
      auto-mode-alist.

    - A second function autodetects image types that do make sense to edit
      (ps, xpm, xbm).  If autodetected, set up the editing mode and turn
      on image-minor-mode.

    - Otherwise, use auto-mode-alist.

I have no objection to this method.
