Abstract: Methods and systems for sharing digital information, such as photos, that include creating a viewable medium or website associated with an event using a computer interface. An identification module is provided at the website or other viewable medium that generates a unique event identifier that may be provided to or received by a plurality of individuals. Photos or other digital files or information relating to the event can then be communicated to the website or viewable medium by the individuals via user devices such that a subset of the information may be accessed at a remote computing interface e.g., by utilizing the event identifier.
