	JavaScript DOM Rollover function

	REQUIREMENTS:
		Image needs to have class="RolloverImg"
		3 versions of image need to be created and stored in same directory:
			imagename.ext
			imagename_on.ext
			imagename_over.ext
		(where .ext can be .gif, .jpg, .png)
	
	USAGE:
		Make sure function initRollovers() is called in the window.onload event (found in /assets/js/init.js).
