An electronic device that includes a touch-sensitive surface stores a plurality of sequences of images. The device displays a first representative image for a first sequence of images in a movable first area on a display. The device detects a gesture on the touch-sensitive surface, the gesture including movement by a contact that corresponds to movement in a first direction on the display. In response to detecting the gesture on the touch-sensitive surface: the device moves the first area in the first direction on the display; moves a movable second area in the first direction on the display; and, in accordance with a determination that sequence-display criteria are met, displays, in chronological order in the second area, at least some images for a second sequence of images acquired by the camera before acquiring a second representative image for the second sequence of images.
