In Dired typing `C-t C-t' (`image-dired-dired-toggle-marked-thumbs')
doesn't show images supported by ImageMagick.
It gets file extensions of supported image types by calling the function
`image-file-name-regexp' and it gets them from the variable
`image-file-name-extensions' that currently misses file extensions
supported by ImageMagick.
I propose a fix that adds them to `image-file-name-extensions'
in `imagemagick-register-types':

There are other packages that rely on image file extensions
defined in image-file.el:

./iimage.el:62: image-file-name-extensions)
./image-dired.el:548: (unless (string-match (image-file-name-regexp) file)

./thumbs.el:228: (directory-files (thumbs-thumbsdir) t (image-file-name-regexp)))
./thumbs.el:411: (directory-files dir t (or reg (image-file-name-regexp)))
I suppose all they will benefit from this fix as well.

You forgot a regexp-quote.

There's something I don't understand:
- why do we have both image-file-name-extensions and image-file-name-regexps?
- why doesn't image-file.el use image-type-file-name-regexps?

I guess for historical reasons.

It seems image-file.el is semi-obsoleted by image-mode.el,
so it should use more general settings from image-type-file-name-regexps.
And other packages should be fixed to use more general settings
from image.el instead of relying on definitions from image-file.el.

Sounds right, though I think that can wait till post-release.
Please go ahead and commit your patch (with the regexp-quote).

On second thought, there is a problem---image-file-name-extensions is a
defcustom, so your patch would trigger a "changed outside customize"
warning if the user tries customizing it after calling
imagemagick-register-types.

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.

This was seven years ago, but the patch wasn't applied. I know that
ImageMagick is slightly semi-deprecated now, but I think this patch
possibly makes sense anyway.
I don't use the Dired thumbnail stuff, though. Did anybody have an
objection to this that didn't land in the bug tracker?

There was no hurry in installing this because all widely used formats
are already presented in image-type-file-name-regexps.

Sorry, I can't confirm if the patch still works since I don't remember
how I tested it long ago, so not sure if this change might break something.

I've now done some light testing in an ImageMagick-enabled Emacs, and it
seems to work fine, so I've pushed the patch.
