I'm trying to write my own custom image extension/file for protection. Any good beginner tutorials for this?
Thanks!

I don't know any specific tutorials on writing your own file format, however, I do know a good site that covers a lot of already-made file formats:
www.wotsit.org
You could probably learn from the already-made ones in order to make your own.
Why not take a standard image format, like JPG or PNG, use some existing libraries for coding/decoding these, but encrpt/decrypt the file data using RC4 or the like?
