CONSTITUTION: A server(1) is connected to user terminals(4-1 to 4-N) and vendor terminals(5-1 to 5-N) via a network(3). The server(1) is also connected to a graphics engine(2). The graphics engine(2) is incorporated in the server(1). The graphics engine(2) combines the image data, a scale image and texture data indicating a background supplied from the server(1) into a final image.
