    There isn't much Emacs can do to protect against problems with
    potentially buggy versions of the image libraries, though.  We
    can make Emacs *prompt* the user when something looks ``odd'',
    but how do we define ``odd''?

Each image format has a standard.  If the format does not allow
arbitrary programs, then it is straightforward (though perhaps
substantial work) to validate an image completely.
