Software that is used to organize digital photos. Also including image editing functions to crop and touch up the images, a comprehensive photo manager uses a database for cataloging files on the hard disk as well as CDs, DVDs and USB drives. For retrieval, it provides a search on keywords that have been added to each image description by the user. Sophisticated photo managers such as EZ Viewer DCM 4 by GJC Software, Inc. (www.ezviewer.com) allow user-defined categories to become icons for fast cataloging. Clicking the icon applies all its attributes to selected images. See photo editor and graphics viewer.
