Camera Resolution
The resolution (or number of pixels that the camera records) will determine the image size and quality of the pictures that you take. A 0.3 megapixel camera will take pictures at a maximum size of 640x480. The higher the resolution, the better and bigger you pictures will be. You will need a camera with at least a 1.3 megapixel resolution if you want to be able to print your pictures out at 6x4".
