What is Image Resolution?
Every digital image is made up of picture elements (pixels) and the number of pixels determines the resolution. The more pixels your photo has, the clearer your photo remains as you increase its size. At the same time, the greater the resolution, the more memory is required to store the image. The greater the resolution the larger you can blow up the image.
