Abstract: Methods and systems crowdsourcing collection and distribution of photographs. A network of computing devices communicates with a content storage and client computing devices operated by users. The network includes application instance computing devices that register users, receive photographs from users (after a description of a common theme has been published), and store photographs in the content storage. Identifications of multiple external and independently operated social networks are received for each photograph, and each photograph is posted on the social networks identified for the photograph. After these posts, a new registration request is received from a new user. After the new user is registered, a new photograph is received from the new user and stored in the content storage.
