1. A non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by one or more processors of an electronic device with a touch-sensitive display, a rotatable input mechanism, and a motion sensor configured to sense motion indicative of a wrist raise gesture, cause the electronic device to: receive, via wireless communication, data representing a sequence of images stored on an external device; display, on the touch-sensitive display, a representation of the sequence of images; detect a contact on the touch-sensitive display at a location of the representation of the sequence of images; determine whether the contact has a characteristic intensity above a threshold intensity; in response to a determination that the characteristic intensity is above the threshold intensity, display a user interface menu including a user interface object, wherein the user interface object represents an option to display a background of a user interface on the display of the electronic device based on the sequence of images; detect a selection of the user interface object; detect, with the motion sensor, a motion indicative of a wrist raise gesture; and in response to detecting the motion indicative of a wrist raise gesture, display the background of the user interface on the display of the electronic device based on the sequence of images, wherein displaying the background based on the sequence of images includes: display, in sequence, a first set of two or more images from the sequence of images; and after displaying, in sequence, the first set of two or more images from the sequence of images, maintain display of an image from the sequence of images.
