    // For example, if the following image needs to be swapped, simply name it with something unique.
    // <img src="images/whatever.jpg" ID='ChangingPicture' NAME='ChangingPicture' >
    // When you call the function, you would simply specify the ID value mentioned above.
    //  Example  onmouseover="SwapImage('ChangingPicture', 'images/some_other_image.jpg')"
