This sets up the two options with id pickImage.
OnServerClick I will execute the subroutine called choose_image.
When the subroutine is executed CISimg.Src is shown with the value selected in pickImage.
Initially the right side image (CISa.gif) is shown.

This code sets up two radio buttons to use to determine whether you want to see the image right side up or upside down. When executed the subroutine checks to see if the first button with id=right is checked if so the image is displayed right side up, else it is displayed upside down.
