Systems and methods for sequencing electronic files include generating a first file sequence and one or more alternative file sequences. An alternative file sequence may be generated based in part on a characteristic of a file in the first sequence. The first and alternative sequences may be used in an electronic slideshow that allows a user to switch between file sequences. In some implementations, which alternative file sequences are generated may be determined based in part on a prediction of characteristics that may be of interest to a user.

A system for publishing digital images wherein a mobile device (14) that stores at least one digital image generates output signals in response to operator commands. The mobile device (14) communicates with a source of digital instructions (18) thorough a communication network (16) such that digital instructions are downloaded to the mobile device. The mobile device is thereafter in selective communication with a server (12) that stores digital images, maintains a user profile corresponding to the user of the mobile device, and publishes digital images to at least one digital address (24, 26, 28, 30).

A display apparatus transmits a picture acquisition request for getting picture information to an external image apparatus connected through a predetermined interface to the display apparatus from the external image apparatus at predetermined intervals and gets a plurality of pieces of picture information from the external image apparatus to be displayed. The plurality of pictures may be switched at predetermined intervals, for example, to be displayed, so that the plurality of pictures may be displayed in a so-called slide show manner. A plurality of pictures for thumbnail may be produced from the plurality of pieces of picture information and be arranged together to be displayed in one picture screen of a display device.

A computer-implemented method for automatically displaying variable image content in an image product includes automatically obtaining markers in photos or videos in a user account which includes detecting features in image content of the photos or the video frames and obtaining a marker for one of the photos or the video frames, automatically identifying a sequence of similar photos or videos if the markers detected in the photos or the associated video frames include more than a predetermined number or percentage of common features, detecting a marker in a photo product by a user device when the photo product is viewed by the user device, identifying a marked photo incorporated in the photo product based on the marker detected in the photo product, and enabling photos or videos in a sequence photos or videos associated with the marked photo to be displayed on the user device.
