Everytime i take pictures of my car, and then resize it down to 640x480 (i think?), the pictures come out to be blocky. I have a 6 MP FujiFilm camera, I saw at some store (prolly Ritz Camera) that people should just use 2 MP for digital prints, but wont that come out to be less quality. Also with my camera, you can set it for 1, 2, 3, and 6 MP with Basic, Normal and Fine settings. What MP does everyone set their cameras for and how do you not get it to come out "blocky"
