Thanks, I figured it out already that it hadn’t, but I do see what you’ve done, just took me a few minutes to figure it out once I inverted one of the thumbs. But posting a demo would be a good thing.
Like I said, it’s a really good find, but I’m not sure that I want to go away from .pngs/.jpgs personally. But it might be worth implementing into a version my themes so SMP users and HUB users with more current firmware can see the thumbs as they are intended.
