Write your terms in words a guest will read
Guests own the photos they take. If you want to use them, they need to agree, and they need to understand what they agreed to. Three sentences beat three pages.
Say what you'll do (post on your channels, use in a recap), what you won't (sell them, use them in paid ads without asking) and how to get a photo taken down. Then show those terms before a guest's first upload, not in a link nobody opens.
Run your wording past whoever handles legal for you. Then make it shorter.
