On a PC, it’s easy to load a folder of images directly into PowerPoint. With your presentation open, click on Insert in the menu bar, then click on Picture, then New Photo Album… This option lets you select an entire folder of images to add to your presentation. To learn more, download the VRC’s Powerpoint Manual for PC (pdf).
Macs do not have a built-in photo album option. You can, however, install a simple program to import a folder of images. For a free version of this program, please contact the VRC. Let us know what version of PowerPoint you are using (i.e. PowerPoint 2007, 2008, 2011) and what operating system you have (i.e., Mac OS 10.5).
