This document provides best practices for using images on screens and in print. It recommends using higher resolution images of at least 300 dpi for print and 72 ppi for screens. The ideal minimum resolution for digital images is 2,400 pixels in the smallest dimension. Larger image file sizes do not necessarily mean larger image sizes in pixels but will result in larger file sizes. The document suggests using common file formats like JPG, PNG or TIFF and viewing image properties using the "i" or right-click properties menu to check resolution, file format and size.
