Abstract: Techniques to allow for ease of navigation within a photo browsing interface of a social networking system. In one embodiment, a designation of a first image for sharing is received from within at least one of a single-image view and a camera view. Based on the designation, the first image is added to a communication. The designation may be based on a user selection of an option provided by an interface of a mobile device. The first image may be received from within a social networking application or from within a dedicated camera application. In another embodiment, the privacy level of the communication and the designated images is based on the privacy setting of a user. The communication and the designated images may contain tag data identifying one or more people on a social networking system. In an alternative embodiment, the privacy level of the communication and designated images is adjusted according to the one or more people identified in the tag data.
