Given that the vast majority of image files have an exact amount of
bytes reserved for the different sizes, I would like to see how you
can put a value larger than what those bytes can express there.

(Ostensibly some compressed image file type might be able to exploit
a buggy image library if there's something in the compression algorithm
that said library doesn't take into account and could cause eg. a buffer
overflow in said library when it tries to decompress the data.)
