Subject: 25.0.50;
 image-metadata using Emacs --with-ns prevents *.gif animation.
Date: Mon, 19 Oct 2015 09:29:17 -0700

When using Emacs built --with-ns on OSX 10.6.8, the function `image-metadata` returns `nil` when trying to animate a *.gif file with the built-in image-mode by pressing the return key.  I suspect it is because `valid_image_p` returns `nil`, but I do not know how to test that internal function.

When opening a *.gif image, Emacs successfully displays the first image in the series of multiple images.  Pressing the return key yields:  "No image animation."

OSX has its own built-in image support when building --with-ns, which is why I am able to see the first of the *.gif images.

(image-type-available-p 'gif) returns t, so I am fairly certain I have image support.

Animation works on Emacs for Windows, but not OSX.

Thanks,

Keith
