Depends on who shows the pictures and how many there are and what's on it.
Remember myself, somewhere in my late tevens at a family thing about a new born. We could see the little one live, but hundreds of pictures were forced on us. Including intimate pictures of my aunt pushing that baby out.
I'm not squeemish. I've been attending cows calving and assisting when needed since I was six or seven. I'm not prudish, nor is anyone in m y close family. But a close up look at the private parts of my aunt, while she was telling what we were seeing was too much. I got up and went to another room. I was not the only one.
