On Windows (others too I think), VirtualDub (free) can open
Animated GIF directly, and you can "Save As AVI". Before you do
that, you can adjust the frame rate there. Or save as avi and
open in Windows Movie Maker and slow it down that way. I use
very basic tools but they work smile emoticon VirtualDub also
saves to AnimatedGIF although the file size is much much bigger.
So - there's ALWAYS a way smile emoticon
