wedding album design - how to determine the size and number of images on a page.

One wedding, three pages showing three layouts. 

When an image is very strong, it needs no additional images.

 But sometimes it's fun to have a record of images leading up to the large image.

In the last page, the images are weak in their composition but strong in their emotion so there is no one dominant image. The images are placed to emphasis the diagonals to lead the viewer from, for example, the bride to the groom.
