When you go to a person's profile page; the block titles will say My Photos.  Of course if I am viewing someone else's profile they are not my photos, they are the photos of the person of the profile I am viewing.  If I am viewing Jenny's profile page they are Jenny's Photos, not My Photos.  Yes, one could change this through the language keys but it should be addressed in the UNA release.  Whoever coded this probably wasn't thinking about viewing someone else's page.
