[racket] reading an image from a file?

If you use File|Insert image... you end up getting an image-snip<%>
object. It is a wrapper around a bitmap% object that connects to our
editor classes. A bitmap% object is the raw bits plus a little bit of
information about it.

Probably you just want to use 2htdp/image's 'bitmap' function, tho.
(Or maybe htdp/image's).
