Thanks serk...
The places I've stored images since I lost access to the webserver at
Clemson don't let you store gif animations, so I just made an account
at giphy.
My gopro does 30 frames a second, so I saved off several seconds and
made the gif animation with a frame from every half second using gimp.
gif animations are jerky and can be annoying, but maybe it will be
an easy way to make an occasional animation of a good road

I'll have to learn a good balance of frame rate and image size to
make the image less annoying...
