Content collection navigation and autoforwarding

Systems and methods for communicating and displaying collections of image and video clip content are described. In one example embodiment, a device receives interface information about a group of content collections from a server computer system. When a user inputs a selection of a first content collection, the device displays images and video clips in a sequence defined by the content collection. Each piece of content (e.g. image or video clip) is displayed for less than a threshold display time. When the device finishes playing the first content collection, the device automatically begins playing a next content collection. Additional content collections generated from content submitted by other client devices can be received from the server computer system, with autoforward play of additional content collections continuing indefinitely. Some embodiments include content collections generated by the server computer system, as well as advertising elements or other system images presented between content collections.
