why do you suggest a "colour bitmap" should be represented using jpeg?
-- for screen shots it seems a really unfortunate choice.

as martin did, i too would recommend png for this application; though
i do regularly use jpeg for photos (which is what it was designed for,
i believe).

stuff, just the words going round it -- and we had a definite
instruction that png is just as good for colour as b&w).
