For merely large images, Emacs won't fit into RAM
and will start swapping like mad, resulting in denial
of service that makes it essentially useless.

For incredibly large images, the underlying libraries are
likely to have unchecked integer or memory overflows, dumping
core if you're lucky and having "interesting" behavior otherwise.
Even if the libraries themselves are reliable (a big "if"),
that part of Emacs is less well ironed out, and I wouldn't
be surprised if Emacs proper has exploitable bugs in this
area.
