A server includes: a first image DB that stores a first image; a second image DB that stores a second image having a file format different from the first image; and an image distributor for distributing, in response to an image display request from a user terminal ( 20 ), the first and second images corresponding to the request. The user terminal ( 20 ) includes: a movable image display unit ( 22 ) for movably displaying the first image from the server; a static image display unit ( 23 ) for statically displaying the second image; and a switch for switching the movable image display unit ( 22 ) and the static image display unit ( 23 ). The server further includes a next image distributor for determining a next image that is expected to be displayed after the first and second images for the image display request and for outputting a command signal so that at least a first image of the next image is distributed together with the first and second images for the image display request.
