Sorting images based on their Pixel Dimension.

JPEG compresses an image based on the color information present in the image (2). Thus, the file sizes are not a true representation of how large an image is when displayed on screen. In trying to sort out small images based on their width or height we face the challenge of sorting images which are unusually tall or wide. Hence, sorting images based on their pixel dimension is a more accurate way of sorting images into groups.
