Abstract: A method and apparatus for managing digital images is provided. A collection of digital images may be managed using a digital image system that displays images using groups, stacks, and versions. A group is a set of unordered digital images that may be visually represented, in a first state, using a representative image, and in a second state, by each digital image in the group. Stacks are similar to groups, except that each digital image in a stack has a rank, and each digital image in the stack is depicted in order of its rank. Versions are similar to groups, except that one or more images in the group are derived from another image in the group.

Abstract: A method and apparatus for displaying digital images on a display is provided. A set of items from a sequence of items is displayed. The sequence of items includes one or more undisplayed items that do not belong to the set of items. The set of items are displayed, in an arrangement that includes a plurality of lines, in an order that corresponds to the sequence. In response to user input that selects a particular item from the set of items, it is determined whether the number of lines, in the plurality of lines, that precede the line containing the particular item is less than a first predetermined threshold. If that is the case, a line of undisplayed items that precede the set of items is displayed, while a line of displayed items that follow the particular item is ceased to be displayed.

Abstract: In general, this specification relates to content presentation. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of presenting a first content item to a first device associated with a user; receive a input from the first device indicating that the first content item has been stored in a repository of the first device; in response to the input, synchronizing the repository of the first device with a user account including the first content item; receiving a request for one or more content items stored in the user account from a second device associated with the user; presenting the requested content items on the second device associated with the user including the first content item; and receiving an indication of a conversion event associated with the presented first content item on the second device.

Abstract: This specification describes technologies relating to content presentation. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of receiving an interactive content item at a mobile device; presenting the interactive content item on the mobile device, the interactive content item being presented with other content; receiving a user input associated with the content item, the user input being one of a plurality of available user inputs associated with the content item; identifying a content item action corresponding to the received user input from among a plurality of content item actions, each associated with a different user input; and performing, using one or more processors, the identified content item action.

Abstract: A method and apparatus for displaying digital images on a display is provided. A pile of images that includes a plurality of images arranged in a first arrangement in which at least one image in the pile overlaps with at least one other image in the pile is displayed. Location data that indicates the location of each image in the first arrangement is stored. In response to first user input while the images of the pile are displayed in the first arrangement, without changing the location data, the images that belong to the pile are displayed in a second arrangement in which no image in the pile overlaps with any other image of the pile. In response to second user input while the images of the pile are displayed in the second arrangement, the pile of images are redisplayed in the first arrangement based on the location data.
