Although not everyone puts his or her photographs online, such collections are an interesting layout challenge. Each photo and its associated information forms a small, self-contained unit that nevertheless has to be laid out with respect to the other photographs on the page. In a way, they're like portals, except with each "box" in this portal leading to more information about a photo instead of to the latest headlines or sports scores.
Photo collections are also reminiscent of another, far more common layout challenge: that of a catalog of products for sale via an e-commerce site. In fact, sometimes the photos themselves can be products for sale, which is the assumption we'll be making in this project.
