Images that are brought into AutoCAD® must have the rectangular frame around it displayed if you want to modify the image. Since you usually do not want the rectangle to print, you turn it off. The IMAGEFRAME variable that controls image frame visibility now has three options. A setting of 0 turns off the rectangle so that it does not print. A setting of 1 displays the rectangle and prints it. A great new setting of 2 displays the rectangle so you can manipulate the image, but does not print the rectangle. This is also on the Reference panel of the Insert menu.
