I changed a couple things, not quite sure which one did the trick, and I'm not going to bother tracing back.

1. Shorten .gif names (I THINK this was the thing that fixed it)
2. Add a 2nd part which will be the "static" image after the animation has run the course
3. Change frames from 30 to 20 (it's probably way too slow now, but you can play with that. i'm almost positive this wasn't what was causing the issue)


Additional Comments:
* If this is running on a Captivate, the resolution is 480 x 800; NOT 400 x 800
* Your animation is pretty choppy. I'd have a more subtle animation from frame to frame.
* Image quality isn't too great. Compounded with the above,...I've seen better.

Here's your bootani after I tinkered with it:
AFbootanimation.zip - Remove "AF" from the file name.
(I'm pulling this off my MediaFire by the end of the weekend)
