Take a look at these images, this is the neatest technique I have ever seen! The second image is a close up of the first image so you can see all the smaller images that are incorporated.
You take one of your favorite wedding or portrait images and then the rest of your wedding photos are in small squares throughout your image. So when you stand back, you see the large one of you two but when you come closer you see all of your family, bridal party, ceremony, reception. I love it! I want to hear from everyone, whatcha think?
