If a user specifies a location on a map image, he or she can see an image shot at that location. An imaging apparatus (an imaging/display apparatus 1 or an imaging apparatus 30) placed on a movable body transmits shot image data to a server apparatus together with additional data that includes location information about a photographing point, so that they are stored in the server apparatus. That is, the server apparatus accumulates pieces of image data obtained by photographing in various places by a great number of imaging apparatuses together with the location information thereof. A user of the display apparatus (the imaging/display apparatus 1 or the display apparatus 40) specifies a location on the map image. Then, the display apparatus transmits location specification information to the server apparatus, and the server apparatus searches for the image data based on the location specification information, and transmits the image data corresponding to the location specification information to the display apparatus. The display apparatus receives and displays the image data.
