No, PowerPoint can't handle those formate. In Photoshop, use File > Save for
Web and choose PNG or JPG. Your camera probably takes very high resolution
(large in pixels) photos that are intended to print well. However, they are too
large for display on a computer or digital display and a lot of the image data
will be discarded when the image is displayed. Carrying all of that data in
your presentation file will make it too large. You'll want to resize the images
to something reasonable for PowerPoint, thereby keeping the file size
reasonable. There is a discussion of this at:
