Photoshop CS6 (Mac OS X 10.6.8) does not (1) save any metadata for GIFs with "Save as..." or "Save for web..." even if in "Save for web..." you select "All" for metadata inclusion. And (2) does not save icons for GIFs.

GIF doesn't support metadata, with or without SaveForWeb.

Save/Save As save icons/thumbnails depending on your preferences settings.
SaveForWeb never saves icons/thumbnails.

According to Wikipedia, the GIF format does support "application-specific" metadata. When I created GIFs using Photoshop CS3, the metadata was retained and showed both the (c) symbol next to the file's name at the top of the file's window and showed the metadata when choosing "File info...". I have attached such two GIFs -- one (Listen CS3) and one (Listen CS6).

As far as icons/thumbnails, I have the preferences set to include these, and (at least on a Mac) a GIF created with CS3 showed the icon/thumbnail on the desktop and in finder windows. The icon/thumbnail is *not* shown in either finder windows or the desktop when saved with Photoshop Extended CS6. I believe this is a bug with CS6.

Finally, if the GIF format does not include metadata, why is there an option to include various types of metadata in "Save for web..." when GIF is selected as the destination type???????

Well, it seems that when you grab the GIF off of a website, the metadata is gone. However, when you create GIFs in Photoshop Extended CS6, the metadata is not included at all. It was, as I said in the post above, included in CS3 when I saved it on my Mac.

However, the thumbnail issue seems more complicated. When I dragged the (Listen CS6) file off my website, the icon/thumbnail appears on the desktop.

So, clearly, there are a few bugs in CS6 regarding GIFs.

That's because the Macintosh can include some extra data in resources, which won't go on the website or Windows. But Apple is trying to get rid of resource forks, so Photoshop is not saving as much into them anymore.

GIF itself does not support any standardized metadata, and rarely gets even application specific metadata (it would break lots of GIF readers).

SaveForWeb shows some of the options for all filetypes.

And if you are saving thumbnails but they do not show in the Finder - then you're seeing a Finder bug (already documented in other topics). This seems to affect some people, in some folders, and goes away when the folder's icon/metadata caches are cleared with utilities.
