ok, quick and dirty:
you'll need to convert to 8 bit. So for each byte read in,

you'll need to bit shift it, and && it so that for each bit, you write out 1 byte, either FF or 00 to a temporary buffer. Then use that buffer to write the jpeg. But I would quietly predict that they look awful. I really can't see JPEG not messing up on b&w images.
