A method for transmitting media, data, and text files in a manner that minimizes the use of bandwidth and memory comprises a BSP file containing a picture of the contents, as well as links to the content of the various components. When the recipient opens the message, the total visual content and all functional objects are depicted in the message display. The recipient may interact with the displayed content and functional objects; as these interactions create a demand for more data on the message content, the BSP file is queried for links to that content, and it is transmitted from the sender, as required by the recipient.
