When image information is transmitted from a first communication device, a server acquires a storyboard ID, a user ID, a photographing date/time, and the like contained in the image information. Furthermore, the server compares the storyboard ID and the user ID with the storyboard ID and the user ID in the storyboard information, specifies the registration destination of the image registration information corresponding to the image information, and registers them. Furthermore, the server generates a layout screen on which the images are displayed in chronological order based on the image registration information and the layout information.
