UnFREEz is a high-speed Windows application that will take any number of images, saved as separate GIF files, and create a single animated GIF from those images. What makes this program unique from its competitors? First and foremost, UnFREEz is freeware, which means you may use it forever without paying a cent or feeling the slightest bit guilty. Secondly, UnFREEz is incredibly tiny, meaning you don't have to spend forever downloading an extremely bloated piece of software. Finally, it is so easy to use. Just drag and drop some GIF files from Explorer, set the frame delay time, and hit Make Animated GIF. UnFREEz will take care of the rest, including automatic interlacing and transparency detection.

Not bad. Very simple, but editing .gif speed seems to be omit.
Simple, easy, free. Great tool for making .GIF's if you're just starting out and of course can combine it with your photoshop skills.
