The category will display the first image on the page that is at least 130px by 115px and used on no more than 10 pages.

The class images were appearing on my category page until I added this to every dragon page: http://riseofberk.wikia.com/wiki/Template:Quick_Links

Now those class images appear on every dragon page and are not used on the category page.

Hope that helps!
