It is a misconception to think that you "need" lots of MP to take good pictures. Not the case! You really need only 0.5 MPixels! This would give you about 800x600 pixels, just fine for display on other members screens!
Now if you would want to print them, you should go up in your requirements, perhaps to 1 MP for a 4x6.
Okay, okay, there are no 0.5 MP cameras anymore. What I am trying to say is, the more important thing is optical quality. Often you will find a better optical quality with higher pixel counts (and higher prices), but it is NOT correlated.
Friends of mine have 4 MP cameras made by xxxxx (big famous computer and printer makers...) and even though the pixel count is great, the optical quality bites, and sharp macro pics are not really possible.
I found that camera manufacturers with a long history in optics (Canon, Nikon, Minolta, Olympus) produce superior cameras compared with those made by manufacturers of copy machines and computer screens
