I would have recommended poweroftheforce.com but it's sadly no longer maintained as the creator, Ed Lee, passed away a couple of years ago. You can however still get most of it through the wayback machine: https://web.archive.org/web/20170319070003/http://www.poweroftheforce.com/
Most pages take a while to load but I had a click around just now and the majority of the images appear to be archived.
