	// To use you put in a handler in the <a> tage wrapped around the graphic you want to swap or trigger the swap. The first argument
	//  is a string containing the name of the parent layer. If there is no parent layer you just enter null. The second argument is a string containing the name of the layer the image is on.
	// If it's not on a layer, simply enter null. The third argument is a string containing the name of the image you want to swap, declared ias an attribute of the <img> tag marking up the image.
	// The fourth argument is a string containing the name of the image (declared in the preload function above) you want to swap it with.
	// eg <a href="#" onmouseover="changeImage(null,null,'imageA','imageA_on')" onmouseover="changeImage(null,null,'imageA','imageA_off')"><img src="image.gif" name="imageA"></a>
