Abstract
Group keys and image group names of image groups to which the owner of a digital camera belongs are transmitted from a server to the digital camera. The image group names are displayed in list form and an image group name is selected from the list. The group key of the selected image group is transmitted from the digital camera to the server. The server sends the digital camera access information for accessing the user computer of another user who belongs to the image group identified by the received group key. The digital camera accesses the user computer based upon the access information and receives the image file desired.
