Could I also recommend "Rapidshot 1.7"? I've used it for ages in MS FlightSim, but as it runs in the background it can be used in any game or other software. Hit the (selectable) command key and it sticks a nice screenshot in whatever folder you've decided to keep your pics in (jpg or bmp - at your choice).
Very useful and it uses hardly any memory.
