the curators for these museums are obviously kiked beyond belief
but the archivists are not, more often than not they're old nerds who insist on preservation, and so if you go to the smithsonian website and other sites, you can freely find and download the pictures
here's the link for smithsonian (if you don't trust it just go to the smithsonian website si.edu) for skulls in public domain, insane amount of stuff to dig through.
