Anons need to remember that Q said all pics are original, not that they are originally taken by HIM. He also said they were either taken by them or wiped from somewhere else.
So with the Vegas pic, for instance, I could see him swiping that off the device of a black hat and posting it as a way to say "we see you".
Or in the Singapore pics, it could've been pics taken by black hats who were scouting the location for position to strike, so Q not only posts them, but then has Kim go take a pic in the exact same spot.
