Conceptually pretty simple, although I wouldn't understand the inner
details of the code. Take an image where all pixels are just one color.
You can describe it completely in a handful of bytes. Take one where
every pixel is very different from all of its neighbors. Even with
acceptance of lossy compression, where subtle variations in color can be
ignored, it is virtually uncompressable without major loss to the image
appearance.
