Heres a nice project for animation in Strips files.
A Strip files are a normal images files, but the image have some separed subimages (in same image) inside.
these project shows you how you can do that animation. some code are in portuguese, but i think that you can get the idea. the image isn't in project mode, by image path. but when you execute the project, you will see the image.
accept sugestions and otherthings.
