|GNU Image Manipulation|
Program (AKA: GIMP)
Despite the awful acronym, The Gnu Image Manipulation Program is a decent image editing program—a free alternative to something like Adobe's PhotoShop (which is awful SAAS now). Another (Windows-only) alternative that's popular is Paint.NET. And the drawing tool Krita has a lot of feature overlap.
There was a project/fork of GNU IMP based round fixing the name and improving the program generally called Glimpse, but development on it has stopped (though if you can download a copy it works great) to work on a new take called Glimpse NX.
Gnu IMP can already create animated GIFs (each layer becomes a frame), but there are some tools to make the process easier.
