I learned it when i was 9 or 10 years old at school..i was in an informatic program..and my teacher taught us how to do it with a program which i don't remember the name..it was pretty funny at this time
Well i just combine widows movie editor and Imageready Cs2(cracked version) and inport the folder of still as frames and it works. I found Photoshop cs2 pretty easily on a bit torrrent site
