Yes, the issue with the Wikipedia one I mentioned in my last reply. For the Star Wars.com, you have to keep it as is. The shorter link form only works for certain sites and Star Wars.com isn't one of them.
Okay. So the way we did if for Wookiepedia and other Fandom wikis, the image on your wiki will change if they change their favicon. What I am saying is that if Star Wars.com changed their facivon, the image on your wiki might not change.
