Using only one image when voting

I use 1-5 voting and have custom images set for voting, i.e. I have a clear image and color filled image. The template for showing the result (%RATINGS_IMAGES%) works fine. What I would like to have is to only use one image for voting (%RATINGS_IMAGES_VOTE%). I mean not showing the current average on voting (for ex 3 filled and 2 clear images) since it is very confusing for tablet/phone users that can not hover over the images.
