A system includes a communication module that receives a request to post content to an event gallery associated with an event. The request in turn includes geo-location data for a device sending the content, and identification data identifying the device or a user of the device. The system further has an event gallery module to perform a first authorization operation that includes determining that the geo-location data corresponds to a geo-location fence associated with an event. The event gallery module also performs a second authorization operation that includes using the identification data to verify an attribute of the user. Finally, based on the first and second authorization operations, the event gallery module may selectively authorize the device to post the content to the event gallery.
