I figured it out and I can definitely help out if you haven't gotten it yet. Just let me know. Be happy to help if I can.
so in the una gallery you enter in the room right after the crowd surrounding the Island picture you go to the bottom middle and you'll get stopped by a security guard. Once he leaves you alone you go and startle the receptionist at which point he'll scream. After that go back to the room where you got stopped by the guard and enter that small room. It's designated by pink squares. Once you're in there got to the topmost middle part of that mini gallery and choose to 'get to close" after that enjoy. Hope this helps.
