Producing animated gifs with GIMP

GIMP ("GNU Image Manipulation Program") is a free graphics program that's on our Teaching System. It has so many features that it's not always easy to find what you want. Here's how to produce an animated icon for a WWW page.

  • To save the file, use the Save option in the File menu. You'll need to have .gif on the end of the file-name, and you'll need to choose Save as Animation when the Export panel appears.
