This document discusses managing photos in the digital age where photos are often shared online. It notes that while photos are shared on social networks and archived, important contextual information gets lost over time, making photos difficult to find later. It then introduces Clickstream, a photo manager that links photos to information from social networks and other sources to make photos easier to find by adding tags and relating them to other activities from the photo's time period. This helps users locate photos years later when important details like the date or event are not easily remembered.
