Disclosed herein is an image service system that is capable of dividing the service into an images managing service and a printing service while maintaining the convenience to the user. When a printing processing portion of a first managing server or a second managing server receives a print command from a user's mobile phone, the URL indicating the storage location of the image data as well as the printing conditions are sent to a printing server, the printing server and the user are connected, and the printing related processes are performed by the printing server. The printing server prompts the user to enter the printing conditions, ands sends over a network the printing conditions and the image data downloaded from the location indicated by the received URL to a printing apparatus, which prints out the image(s).
