- * NOTES:
- * 04/01 - 04/10: been working on it a lot. I think it does gif89 images just
- * fine with palettes. So that's cool. Putting in multiple
- * images and animation support right now
- * 03/29: For some reason I can write .GIF files which IE will open and see
- * but kodak imaging does not like. I'm sure its a problem with the GIF
- * file, I can't figure out what.
- * 03/17: Explicitely deallocate the GIFTOMEM* struct in the main loop.
- * Check for both success and failure conditions
