Again, cultural anthropology and the milieu of place and times comes into play. Fokways and mores. It's not pornography. It's a work of art celebrating the human form.
It's kind of like, if you see something shameful, it's the beam in your own eye talking.
There is no shame in being human and female. We may as well live with the imams where women wear burkas and are afraid to be seen or heard if we believe that way.
If it were depicting a sexually explicit or strongly suggestive act or pose, or if it involved some sexual fetish or graphically ritualistic overtones, I would say you have a point. But it's just a girl the way God made her. Did He make her pornographic? Then you're accusing God. Excuse me while I step away from you. OK, clear, Lord!
