Full Review

I was taking 5 Mega Pixels pictures with my camera when the battery went out. I turned it back on and saw that the camera had been reset to 3MP. When I try to change the resolution back to 5MP, the option is gone so is the option to take 4MP. The highest it can go was 3MP. I've changed the batteries, turned it back on and off several times since then and I can't get the option back on. I don't don't how to fix this malfunction. I've only had it for 2 months and I hardly used it!
