My animated GIF of photos looks AWFUL

[Ofnuts]

Also, best not use Gimp for this... Gimp only supports the original GIF format, with a color map of 256 colors common to all frames. A more recent extension of the format allows a 256-color color map per frame. The old format isn't much of a problem for real animations where all frames are variations of the same and therefore share a lot of colors, but doesn't really cut it for slide shows.
