Techniques are described for displaying projects of images as “collages”. Collages differ from conventional thumbnail displays of projects in that collages display an entire project as if the project were a single image. Consequently, collages better convey the characteristics of projects as a whole, while de-emphasizing the distinctiveness of individual images within the projects. When displayed as collages, side-by-side comparisons may be readily performed between projects as a whole. For example, a single display may include collages for multiple projects, thereby allowing viewers to quickly tell how the projects differ in a variety of ways, including but not limited to size of shoot or density of shoot, dominant color, mood, time of day, bracketed shots or bursts, location and subject matter. The content of the collage for a project is based on the individual images that belong to the project. However, details of the individual images on which the project image is based may not be readily discernible from the collage. In addition, not all individual images that belong to a project may be used in a collage. Techniques for selecting which individual images of a project to include in the project are also described.
