Image Resolution

Resolution, also known as DPI (Dots Per Inch) or PPI (Pixels Per Inch), can be described as the number of dots that fit horizontally and vertically into a one-inch space. Generally, the more dots per inch, the more detail captured and the sharper the resulting image. But don't go overboard as your file size will quickly get huge.
