To allow a user to easily obtain the information of a service content provided by a photo studio or a laboratory to which the user is requesting a service at that time, and to easily prepare an order file based on the information when the user prepares the order file to be transferred to the service provider by ordering by his own personal computer for a digital photo service.

A service item displayed on a screen by application software for preparing an order file is described in an item reference file 7 different from the application main body, and each time the application main body is executed, the time reference file 7 is read (a step 403), and the service item described in the file is displayed. That is, the item reference file is provided as another file different from the application main body so that the service item displayed on the screen can be changed only by replacing the item reference file.
