All imagery should fall under copy right free and public domain.
When including imagery or creative collages, it is important to consider the following aspects when the image is of a person.
Is the person famous? If so, what are they famous for? Do they align with the feeling and sentiment of the brand?
Asking these three questions help steer the choices of who is included on brand imagery. Diverysity should also be a key consideration.
People should be interacting with something or in a notable environment, with no obvious outside brands present.
