With my patch they can.

Images are (currently) perfectly valid lisp values; if we don't want
them to be readable and writable to files, we should make them an opaque
type.

But that seems like a stupid thing to do.  Just make the C code deal
with the situation.  If my patch was wrong (though I admit, I still have
no idea why -- your discussion so far doesn't make much sense to me),
fix it, but don't remove the functionality it adds.

[Note that reading and writing images to files (and displaying them in a
new emacs instance, by just reading the file) worked fine before the
changes that added Finit_image_library etc., so the bug I fixed is a
regression.]
