Image/File Compression

hey /prog/, an inquiry here, for anyone who knows anything about image compression.
Long story short, me and a few other people are working on a hitbox/frame viewer for Guilty Gear, as well as extracting the Gallery images.
We've successfully extracted the images in binary form, but we can't make sense of them, there appears to be a compression on the images. Does anyone here have any experience in this field?

All I said was they're proved ``deductively" which is pretty ambiguous. I don't want to argue about the philosophy of maths.

You misunderstood. I mean you just take them to be true until a contradiction is found.
