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?

It isn't open. Universe is finite, therefor deterministic.

Otherwise can you imagine a “physical process” whose outcome could depend on whether there’s a set larger than the set of integers but smaller than the set of real numbers? If so, what would it look like?
