It's been a while since I used Pages, but the last time I used it, I dragged and dropped a photo into a blank document and there were options to add nice borders to the photo.
Specifically, I added an effect which made the photo look like it was peeling off the page on the left and right side, and there was a shadow underneath each corner giving it a 3d appearance.
I can't for the life of me find that feature in Pages (using Page '09).
