Not meaning to sound like a broken record, but here on the interwebs, keeping image sizes at a moderate level is usually appreciated. Something like 100..200K per image tends to be fine (typically that's what you get with about 1024x768 and a decent JPEG quality setting like 90).
BTC foam and foil jobs are not the very most popular since the feel is kinda meh, but they do sport NKRO, which can be handy in certain applications (e.g. music input).
