Several possibilities, but none of them are really a "link".   1. Put the image into the symbol and set the class to all of the images to the same class. When you Recalculate the worksheet, make sure the class the image(s) are in is turned on and the classes that the other parts of the symbol are turned off.   2. Put the images into individual symbols. Store the symbol name in a Record.Field attached to the symbol. You should then be able to use the name of the "image symbol"
