Common law trumps other law. I mentioned that elsewhere:
REGISTER, common law. The certificate of registry granted to the person or persons entitled thereto, by the collector of the district, comprehending the port to which any ship or vessel shall belong; more properly, the registry itself. For the form, requisites, &c. of certificate of registry, see Act of Con. Dec. 31, 1792; Story's Laws U. S. 269 3 Kent, Com. 4th ed. 141.
Who do you think "owns" those images if you register them?
