But it looks horrible, there's a lot of dithering.

  It looks perfect in Firefox and Chrome and IE and locally, for me. The slightest of banding on the tab, now I come to look for it. I guess you're using a browser that doesn't render animated GIFs very well.

    I tested on Chrome 23, Firefox 15 and Safari 6 on Mac OS X. All the same result. Edit: looks the same in Photoshop too: http://i.imgur.com/nu90E.png http://i.imgur.com/nu90E.png

      That's really interesting. I'm on Windows 7. Just tested in Debian Linux and it's fine there too. Must be a Mac issue? (Edit: I confirm that I can see faint green spots all over the background in your Photoshop screenshot.)

        Likely. I remembered OSX used to have few issues with GIF rendering in Core Graphics, but I'm sure Chrome and Firefox aren't using Core Graphics for GIF rendering. Strange.

        Looks fine in FF on my MBP!

        Looks fine in Chrome on my MBA as well.

        Could it be just because we've got our monitors set to different gammas? Here's a frame from the animated gif, which still looks fine to me: https://picasaweb.google.com/lh/photo/oaNDcnogej-bbrArcXuzK9MTjNZETYmyPJy0liipFm0?feat=directlink https://picasaweb.google.com/lh/photo/oaNDcnogej-bbrArcXuzK9... Does this look dithered to anyone?

        This one looks perfectly fine to me. Gamma 2.2 (Mountain Lion default).
        tim_hutton 14y ago
        OK. Well I guess this supports the original poster's motivation, that animated GIFs can't be relied on.

        This one looks good to me. Animated gif, on the other hand, does look dithered on its background. Ubuntu 12.04, Chromium 18.0.1025.168.

        I have the same issue as sirn on Firefox on Win7. edit: also chrome and IE.
        tim_hutton 14y ago
        Just a thought - are you in True Color (32-bit) mode?
        sp332 14y ago
        Yes. I'm guessing gamma is to blame here.

  Looks fine in FireFox 10 ESR on Solaris 11.
sp332 14y ago
If you turn off dithering, the colors might be less "accurate" but it should compress better. Color accuracy doesn't seem to matter so much in this application so it should be acceptable.
- tim_hutton 14y ago
  By converting to indexed color first (in Gimp: Image > Mode > Indexed) we can turn off the dithering. I would be interested to know if this looks bad on anyone's screen. http://picasaweb.google.com/lh/photo/asf1q9Da0w0PwN8PoadpVtMTjNZETYmyPJy0liipFm0?feat=directlink http://picasaweb.google.com/lh/photo/asf1q9Da0w0PwN8PoadpVtM...
