PowerPoint 2004 and 2007 for Windows has a feature called 'photo album' which allows you to load in groups or folders of images, and resize them to screen-size all in one step. This fantastic feature is not included in Mac versions of Powerpoint, but a plug-in exists which will do the same.
If you have PP 2004 for Mac, download and unzip this plug-in.
If you have PP 2008 for Mac, download and unzip this plug-in.
Please contact me if you have questions or need help, because these do not work with all operating systems.
Also, available for a small fee, you may download similar scripts for Macs running PPT 2001, 2004, and 2008 from this site: http://www.agentjim.com/MVP/PowerPoint/PPTHome.html
