US Patent 7996756 System and methods for displaying user modifiable server-rendered images

A system and method renders an image on a server and displays it on a client. A server sends to a client a web page that includes a design document encoding graphic elements that characterize a design image. The client receives edits to the graphic elements, and sends the design document back to the server. The server then uses the design document to render an image, and sends to the client the rendered image for display in the web page. The web page may contain an IFRAME markup tag to define an area in which to display the rendered image. The server may use a database to store the rendered image and use it in completing a customer order.
