There are three main factors that determine the size of a photo: the number of megapixels of the photo, the type of photo and whether the photo is uncompressed. The more megapixels a photo has, the more room it takes up. A 4GB memory card holds nearly 1,140 photos at 10 megapixels apiece but only 520 photos at 22 megapixels.
