Buddy:
First, if you’re not already familiar with
VersionTracker.com, do become so. It’s a great way to track down esoteric software. You’ll even find at least one GIF animation app there.
Second, interesting question. While animated GIFs certainly do still work, they don’t get a lot of love any more because of their limited palette, poor efficiency and the lingering taint of noxious patent litigation.
There used to be ways to create animated GIFs from within Photoshop, or rather, the ImageReady application that was once packaged with it. Adobe Fireworks used to have that capability, too. I have no idea where that functionality currently resides in CS4, or if it does at all.
Assuming that you need redistributable media (for the Web or whatever), these are the alternatives that I know of:
1) video (e.g., quicktime)
2) Flash
3) javascript-controlled (dynamic) animation
The video option means you'll assemble frame stacks using some sort of tool that will then render out a video file. Definitely take a look at
iStopMotion. You can download a free trial. I’m not positive it will do what you need, but it might, and it’s pretty nifty.
Flash is flash. Adobe’s Flash CS4 product is the obvious tool.
Javascript-controlled animation that is delivered dynamically by web browsers is growing in stature and sophistication. Here's
a simple example that popped up first in Google. I don't know if there are any interactive authoring tools, yet, or not.
Hope this all helps somehow.
