Embodiments for communicating and displaying collections of image and video clip content with an opt-out interstitial 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 is displayed for less than a threshold display time. When the device finishes playing the first content collection, the device presents an opt-out interstitial. Additional content collections generated from content submitted by other client devices can be received from the server computer system, and are presented based on a response input, or a lack of response input, to the opt-out interstitial. Some embodiments include content collections generated by the server computer system, as well as advertising elements presented between content collections.
