Seeking clarification on copyrighted material in photos

I understand that reviewers aren't expected to be copyright experts, but I was wondering if there's been additional guidance on what can appear in photos.
For example, I would assume that this is not allowed because of the characters shown, but maybe "fanart" would be considered acceptable?
As another example, not fanart but rather officially licensed depictions. I saw a nomination for this rollercoaster and wasn't sure if it would be allowed due to the intellectual property.
Copyright stuff can really get into splitting hairs, but just wondering if there's been any additional guidance on more clear-cut situations.

Don’t worry about copy right stuff for nominations. If its a third party photo or a watermarked photo then no. This stuff is perfectly fine
Its your own picture as long as you make an own one. 3rd party means that you took a picture out of the Internet.
Thanks, guys. That's a lot easier than what I was overthinking it to be.
