Then we could change the function `image-file-name-regexp'
that dynamically constructs a composite regexp from
`image-file-name-extensions' and `image-file-name-regexps'.
What we could do is to add to its return value a regexp added
in `imagemagick-register-types' to `image-type-file-name-regexps'
with the assoc value `imagemagick':

This is a temporary solution for the next release of 24.1 that
will allow image-dired.el to display Imagemagick supported images.

I think in 24.2, defcustoms in image-file.el should be deprecated
and packages should use `image-type-file-name-regexps' instead.
