A method, system, and media are provided for delivery of content from a communication device. A temporal shifting server enables delivery of temporal shifting messages. The temporal shifting server checks conditions associated with a communication network connected to the communication device and determines whether conditions of the communication network support delivery of content stored in a large file. If the communication network can support the large file, the large file is communicated over the communication network to a recipient and a copy may be retained by the temporal shifting server. If the communication network is unable to transmit the large file, the temporal shifting server generates an identifier for the content, transmits the identifier to the communication device, receives a small file that stores a version of the content, and stores the small file.
