PowerPoint Photo Albums
There are many ways to add photos to PowerPoint presentations. However, if your whole presentation is about photos, you can use the photo album feature in PowerPoint, which makes the whole process fast and easy.
Make separate digital photo albums for different sets of pictures. There is no limit to the number of albums, or the number of photos in each album. This is a great way to organize your photo life.
