PROBLEM TO BE SOLVED: To solve the problem of delivery of image data related to a file screen shared between an expositor A and a viewer B requiring labor of both the expositor A and the viewer B.

SOLUTION: An expositor terminal 1 of an expositor A determines whether a designated position (x, y) designated by a cursor c1 by a viewer B on a viewer terminal 3 side of the viewer B is included in a display area of a file screen F1 on the expositor terminal 1 side equivalent to a file screen f1 displayed on the viewer terminal 3 side. When included, the expositor terminal 1 transmits image data related to the file screen F1 to the viewer terminal 3. Thus, the viewer B does not need to tell the expositor A a file name and the like of the desired image data by bothering to use E-mail or the like, and the expositor A does not need to find out the requested desired data, so that labor of the two parties is saved.
