Abstract: An image file is managed by a database of a system of a service provider (center server) on a network. The center server obtains various kinds of information (such as an image ID to specify the image to be transmitted and a destination address) input to the system by a service user who has viewed the disclosed image. Based on this information, the center server reads the specified image file from the database, converts the image file into an attachment document format, generates an image-attached electronic mail message, and transmits the electronic mail message to the specified address.

Abstract: In a network photograph service which provides a digital photograph service on a network, a workload on a user to input a registration ID needed upon viewing an image is reduced. In a registration ID input screen 38, the registration ID and a registration password input to boxes 39 and 40 are stored by relating the two to the user ID of the user who has carried out the input. When the same user recalls the registration ID input screen 38, registration IDs 32 having been stored are displayed as a list. By selecting one of the registration IDs by clicking a display button 41, display of images managed under the registration ID can be requested.

Abstract: Image transmission via electronic mail is carried out more easily and at low cost. An image file managed by a database of a system of a service provider (center server) is disclosed on a network.

Based on this information, the center server reads the specified image file from the database, converts the image file into an attachment document format, generates an image-attached electronic mail message, and transmits the electronic mail message to the specified address.
