An entertainment is provided in which a limited number of persons can share images through a peer-to-peer network, and a device is provided for allowing anyone to easily get a print having a desired finish quality at the nearest lab store with no uploading procedure. A peer-to-peer server enters a closed user group (CUG) and issues a password necessary for login to the CUG. It is possible to share an image between client terminals having the same password through peer-to-peer connection. It is possible to directly transmit the shared image to an order-accepting server of the nearest lab store through peer-to-peer connection and print the image. Moreover, when a user designates an image-processing condition on a client terminal, the information on the condition is sent to and managed by a client-managing server. The lab that receives a print order extracts the favorite information of the client concerned from the client-managing server and provides a print having the desired finish quality.
