Abstract: When a searching of an image file is indicated, a wireless telephone extracts image files and makes the image files to be icons, and displays the icons in a layout on a display unit. When a positional information acquiring indication is detected, the wireless telephone acquires self-positional information, centering on the acquired self-position, leaves only the image files to which the positional information are added, reads place name folders corresponding to the image files, and displays those in a layout. When one of the displayed icons is selected and a network connection indication is detected, the wireless telephone achieves a session with a map information service company, and transmits the self-positional information and the positional information which the selected image file includes, to the map information service company.
