Detailed explanation-2: -A 72 dpi image would have 72 pixels per one linear inch, or 72x72=5, 180 pixels in a square inch.

Detailed explanation-3: -The difference between 300dpi and 72dpi is found in the amount of pixel information (or dots) for every square inch of the image you are viewing. The more dots/pixels the image contains, the sharper the image will print. When designing graphics for commercial printing purposes, your images should be 300 dpi.
