ImageJ for making and modifying pictures

Question

Has anyone used ImageJ? It is free and has a very nice macro programming language that can be used to create or modify images and/or movies. It is used professionally for scientific data analysis and much more. I have used it for many projects with a lot of success and fun.
Try it for yourself and let me know what you think!
