Abstract: A method for event-based photo sharing that is carried out by an application or program executing on a mobile device such as a smartphone or tablet computer. An event that is defined at least by a geographic perimeter and a timeframe is created and stored. Location and time metadata of a captured image are compared to the geographic perimeter and timeframe of the event. The image is associated with the event when the location metadata and time metadata of the image falls within the geographic perimeter and timeframe of the event.
