ShotKeeper

Compared to its many competitors, ShotKeeper hogs too much space and offers too little in return. As an image-cataloging tool, this application's main convenience is that it doesn't actually move images to category folders and lets you assign one photo to several categories. As a viewer, the program is only capable of displaying photos in the full-screen mode or as a thumbnail. ShotKeeper lets you rotate your images and adjust the histogram settings, but that's the extent of the editing toolset. We could live with this program's limited scope in most cases, but it must install the Microsoft .NET framework to function properly, which beefs its size up to a whopping 28MB. This utility does what it promises, but smaller, more powerful options are readily available to those willing to do the research.
