Hi -

You should probably look at Mark Rivers' areaDetector ... he has solved most of the problems with image type data in a very modular fashion.  If your needs are somewhat different just add a plug-able module.

Like you said, a simple waveform could store such raw image data in a BMP format without a header and the clients would then be able to draw it.
