This digital image is 512 pixels in height and 768 in width. The total number of pixels in the image is thus 512 x 768 = 393,216. Since color images are comprised of three channels (red, green, and blue) the total amount of bytes to store the image is 393,216 x 3 = 1,179,648 bytes (or 1,179,648 x 8 = 9,437,184 bits) to store the raw image to disk or a web server.
