Computer implemented method and system for transmitting graphical images from server to client at user selectable resolution

Techniques for transmitting graphical images in a network environment are described. According to the techniques, the amount of data of the graphical images that is transmited is customized in accordance with client and/or server supplied information. The techniques enable graphical images to be transmitted more efficiently than previously possible, thus saving precious network bandwidth and reducing transmision time. The invention is particularly suitable for network (Internet or Internet) implementations wherein graphical images often need transferred.
