Optimizing GIFs

Very nice tutorial, thanks for sharing!
And actually that "dirty rectangle" thing is exactly what I've been thinking about

I wonder if there is a method to put the background in first frame, and leave next frames with transparent background and only moving thing.

Nice to know that there is such method.

I messed with palettes too, but finally ended with a local pallette - PS even have various(and size-varing) methods of making local palette.

Thanks for help, it'll surely be useful if I fancy a new animated avatar ;]

No, you're thinking of the transparent pixels thing (like I was before I read about this dirty rectangle business). Transparent pixels can be individual pixels or big blocks of pixels, whatever is appropriate.
ie The transparent pixel method would still have the frame size at 100x100, but most of that would be transparent & only the area around her mouth would be non-transparent in a given frame.
In the dirty rectangle method though, the entire frame might only be 10x15 pixels, with no transparent pixels at all. That 10x15 block would then get positioned in the middle of the frame (or wherever it belongs).

The transparency Drahken is talking about is performed when you select "optimize animation" under the animation window in CS5, if I remember correctly. I have no idea how to do the dirty box technique though.
