Thanks! That works better, except on portrait type images, it doesn't
maintain proportions--it stretches them to fill the slide. Is there a way to
have the program maintain proportions automatically?

Click "lock picture aspect ratio" in the Format | Fill Effects | Picture
dialog. It becomes available after you've selected a picture (tick it before
hitting OK).
It will probably cut off some of the picture, though.
You can, of course, just use Insert | Picture | From File for those portrait
pix.
If you really need many portrait pix on horizontal slides, you may need to
use a batch importer like Image Importer Wizard. http://skp.mvps.org/iiw.htm
