Lately I've been usin'
Gamani's GIF Movie Gear.
Their descrip:
By relying on substance instead of hype, GIF Movie Gear makes GIF animation building quick and easy. It is not a bloated, slow, complicated app that is a chore to use. What it is is small, fast, and efficient. It gives you the tools you need to get the job done cleanly and effectively. The superior interface shows all the frames of the animation at once, making it easy to see what you are working on. Top quality optimization and color reduction functions keep your file sizes down. Fine-tuning of timing, transparency, cropping, sizing and color palettes is trivial. A variety of import/export options, including GIF, AVI, BMP, JPEG, ICO, PNG and layered Photoshop PSD files, support most common image formats. And the built-in tutorial helps you get started in no time.
