Techniques for grouping images are disclosed. In some situations, the techniques include identifying at least one event-based image group among a plurality of images based on an event that is associated with each identified image, receiving a selection of one or more objects in a first image of the identified event-based image group, identifying other images in the identified event-based image group that each include at least one of the selected one or more objects, and associating the identified images with the first image. In one instance, the selected objects include individuals captured in the image.
