.bmp format is fairly simple, and is well documented (e.g. see
www.wotsit.org).  It wouldn't be hard to write a reader using
connections.

The only difficulty is that several pixel formats are available.
However, if you have control of the creation of the files, you can
choose 24 bit BMPs, which are the simplest to read.
