I recently finished working on my pet Master Chief and I would like to provide credit for the images I've used but I'm not sure how. They came from google search images but are stills of the TV Show Halo by Paramount Studios so how do I credit them properly please? I don't know if they are Copyrighted either ;/ Also how does one credit a TV Show in a pet profile please?

i would put something like "images from Halo (2022)" and "character based on the Halo franchise"
