The invention provides, in one aspect, a multimedia content sharing system that includes (i) a shared content server which stores items of content (such as still, moving images and audio) and (ii) a plurality of nodes, each of which is in communications with the shared content server via cellular telephone and/or other data networks. The shared content server transmits items of content to a first set of the nodes “automatically,” e.g., without requests by users of those nodes for the items. At least one node in that first set displays the content of received items (e.g., on an LCD screen) and accepts user feedback in regard to those items. That feedback—which may be, for example, a command to copy an item into an “album”, to rotate an item on the display, to block another node from displaying the items, and/or to block a sender (or creator) of the item from sending further items of content from presenting—is transmitted back to the shared content server for distribution to other nodes, which alter their own respective displays of the items accordingly.
