For that kind of thing, I don't use a program called "AVI-Creator". You might think it's odd that I say "I don't use", but it's because I have it installed looking like I may have used or planned to use it once, but I don't know that I ever have

. So I can't vouch for it's usability, but I can say that such programs do exist for free. Search for "AVI Creator" and if you can get the images into AVI format, then maybe you can convert the AVI to a more compressed format with movie maker or some other program.
