38.13.4 GIF Images

For GIF images, specify image type gif. Because of the patents in the US covering the LZW algorithm, the continued use of GIF format is a problem for the whole Internet; to end this problem, it is a good idea for everyone, even outside the US, to stop using GIFS right away (http://www.burnallgifs.org/). But if you still want to use them, Emacs can display them.

:index index

You can use :index to specify one image from a GIF file that contains more than one image. This property specifies use of image number index from the file. An error is signaled if the GIF file doesn't contain an image with index index.
