GIMP, the GNU Image Manipulation Program is available as a free download for the Windows, Mac OSX and Unix/Linux platforms. It allows for more than simple image resizing, but this document covers only how to crop and resize an image. This document is offered as a courtesy - the supported and recommended product for photo manipulation at WMU is Photoshop. Anyone who chooses to download and use GIMP, assumes full responsibility for its use.
