I use Imageready myself, but if you're new to the whole thing, Animation Shop is much more intuitive and has a friendlier learning curve. Among other things, it has a wizard whick lets you pick out a series of individual files (like jpegs), set the rotation speed and size, and export an animated gif.

Don't know if Animation Shop is available for download individually, but it's bundled with the trial version of Paint Shop Pro.
