A method, comprising: at an electronic device with a display and a touch-sensitive surface: displaying, in a first user interface on the display, one or more images from a media item that corresponds to a sequence of images in a first display mode, wherein: the first display mode is one of a plurality of user-selectable display modes for the media item that corresponds to the sequence of images; while displaying the one or more images from the media item in the first display mode, detecting a first input; in response to detecting the first input, displaying a display-mode selection user interface on the display, wherein: the display-mode selection user interface concurrently displays a plurality of representations of the media item, including: a first representation of the media item displaying a preview of the media item in the first display mode, wherein the first display mode is configured to display the sequence of images in the media item repeatedly playing forward and then backward; a second representation of the media item displaying a preview of the media item in a second display mode that is different from the first display mode, wherein the second display mode is configured to repeatedly display the sequence of images in the media item in a loop; and while displaying the display-mode selection user interface on the display, detecting an input on the second representation in the plurality of representations of the media item; and, in response to detecting the input on the second representation in the plurality of representations of the media item: selecting the second display mode in the plurality of user-selectable display modes for the media item that corresponds to the second representation in the plurality of representations of the media item; ceasing to display the display-mode selection user interface; and displaying one or more images from the media item in the second display mode that corresponds to the second representation in the plurality of representations of the media item. displaying, in a first user interface on the display, one or more images from a media item that corresponds to a sequence of images in a first display mode, wherein: the first display mode is one of a plurality of user-selectable display modes for the media item that corresponds to the sequence of images; while displaying the one or more images from the media item in the first display mode, detecting a first input; in response to detecting the first input, displaying a display-mode selection user interface on the display, wherein: the display-mode selection user interface concurrently displays a plurality of representations of the media item, including: a first representation of the media item displaying a preview of the media item in the first display mode, wherein the first display mode is configured to display the sequence of images in the media item repeatedly playing forward and then backward; a second representation of the media item displaying a preview of the media item in a second display mode that is different from the first display mode, wherein the second display mode is configured to repeatedly display the sequence of images in the media item in a loop; and a first representation of the media item displaying a preview of the media item in the first display mode, wherein the first display mode is configured to display the sequence of images in the media item repeatedly playing forward and then backward; a second representation of the media item displaying a preview of the media item in a second display mode that is different from the first display mode, wherein the second display mode is configured to repeatedly display the sequence of images in the media item in a loop; and while displaying the display-mode selection user interface on the display, detecting an input on the second representation in the plurality of representations of the media item; and, in response to detecting the input on the second representation in the plurality of representations of the media item: selecting the second display mode in the plurality of user-selectable display modes for the media item that corresponds to the second representation in the plurality of representations of the media item; ceasing to display the display-mode selection user interface; and displaying one or more images from the media item in the second display mode that corresponds to the second representation in the plurality of representations of the media item. selecting the second display mode in the plurality of user-selectable display modes for the media item that corresponds to the second representation in the plurality of representations of the media item; ceasing to display the display-mode selection user interface; and displaying one or more images from the media item in the second display mode that corresponds to the second representation in the plurality of representations of the media item.
