Photos a friend of mine took...

I always though that it was just width x height of the CCD chip in a factor of a million pixels.

So say 1024 x 768 = ~0.7 megapixels right?

Wow, photos are really amazing!

Well here is the camera I have Canon 10D

MegaPixels are calculated as: W*H*B=MP or Width*Height*BitDepth in low end cameras (consumer). In Pro-line or Pro-Sumer cameras (such as the 10D, 20D, 30D, D100, etc...) its W*H as B is a static measure. Thus you really do get what you pay for and a 10MP Pro has a better resolution and color depth then a 10MP consumer.
