I used 7 photos for this page. I thought this layout was great because of the flexibility. I could have used more pictures on the right and left, but chose to stick with two. In the top right and top left a portion of each picture is left whole and a portion is tiled. That took a little more calculating because I wanted the images to line up, especially since it involved body parts. But again, comprehending "squares and gaps" keeps it far from rocket science!
