Whats the difference between a web image (72dpi) and a print image (300dpi)?
On the web, smaller images (usually saved at 72 dpi) are used, in order to cut down on loading times and maximize storage. These smaller images look fine on the web because a limited number of pixels are used to compose an image. However, a printer needs more information than your computer monitor in order to create a realistic image. Therefore, print files need to be 300 dpi or better.
