Reply #4: There's no way a camera as tiny as the Optio M20 is a true 7mp.

The CCDs in those things are just too damn small for that kind of resolution. Which means the camera interpolates (or the pixel numbers are otherwise fudged), which means you aren't getting any more actual image detail at the higher settings, just crowding your chip. I'd do 2 things if I were you: one, leave it set at 3M or 4M, three stars, which will be plenty of res to make 4x6 prints from, and two, get a bigger memory card. I just got a high-speed gigbyte CF card at Best Buy for like $35 with rebate. With storage getting so cheap, there's seriously no point in being stingy with your shooting, the way you'd have to be shooting fake-7M on 128MB cards.
