How are you doing this?
There are several methods:
1. Select a thumbnail and drag and drop on to an existing album.
2. Select thumbnails and right-click on an album and choose add selected items to album.
3. Select thumbnails and start a new album by clicking the green plus symbol.
PS The trial version is identical to the purchased version.
Thanks, I follow all these procedures but when I attempt to drop photo to the frame I receive an error with a red X "Place Photo In Frame"
OK I get it! When you say album you mean book, sometimes referred to as a photo album.
Try switching to advanced mode and then open the layers pallet:
Window >> Layers
Select the layer with the empty place holder (so that it is highlighted) and then try dragging an image from the photo bin.
