Even better, store it as a .gif (4 bits = 16 colours greyscale) or .png.
Jpg is best for photo-realistic images, whereas .gif does best on line
drawings, text, other such high-contrast stuff. Png is somewhere in the
middle, trying to accomodate both within the same file format.

Good suggestion. I've found that GIF is by far the best on B/W line drawings,
and even Microsoft Paint mitmap output with 4 or 16 colors, but I still mean
line drawings.

However, on a grayscale photo, even when cut to 16 shades of gray, I find GIF
files are bigger than JPG. Best is to try both schemes. pick the smaller file.

Don't know how much software can handle PNG format, though that may be the new
format that someone helped me test on my photo viewer last month.

Oh yes, I have two really old pieces of Clough-Brengle test gear -- a signal
generator with a rotary turret bandswitch (very compact, though), and a
motor-driven wobbulator sweep generator. They are both AC/DC, so I've been in
no hurry to try them out :-)
