1. A method comprising: by a computing device, automatically and without user input grouping one or more images captured by a first user into clusters of particular moments based at least in part on metadata associated with one or more of the images or data determined through analysis of one or more of the images, each particular moment being associated with a particular geo-location and time; by the computing device, for one or more of the clusters, determining curating information comprising information identifying one or more second users present at the particular geo-location and time, the determining being based at least in part on: social-graph information associated with the first user; social-graph information associated with one or more of the second users; and socially relevant activity of one or more of the second users that is related to the particular geo-location and time, wherein the social-graph information comprises a social graph including a plurality of nodes and edges connecting the nodes, and wherein at least one node in the social graph corresponds to the first user and at least one node in the social graph corresponds to one of the second users; and by the computing device, providing, for each of the one or more of the clusters, the images and a selected portion of the curating information for display on a computing device of the first user, wherein the provided curating information identifying one or more of the second users present at the particular geo-location and time is selected based on one or more edges in the social graph connecting one of the nodes corresponding to the second users to the node corresponding to the first user.
