If you click on a photo in your ideabook, you'll see "add to Ideabook" below the photo. Using that, you can add the photo to a different ideabook. If you then want to delete the photo from the previous ideabook, you just click on the "X" and that will do it. Very handy features.

Excellent! Thank you! We are a little new to the website but we absolutely love it for design ideas!
