Listing content is transmitted from a wireless mobile device to a server, where it is automatically posted in a listing database and made available on a network, such as the Internet, to third parties. The listing content may include both image data, captured by an integrated camera of the wireless mobile device, and text data, input by a user of the wireless mobile device. The wireless mobile device may provide an interface on its display to facilitate the capture of the listing content in discrete data components. After capture, the discrete data components for a single listing may be automatically associated together such that it is unnecessary for a user to manually associate them. The captured listing content may be automatically transmitted to the server in response to a single user selection received through the interface on the wireless mobile device.
