When there will be a wedding picture from Auschwitz in mywed timeline?

I was looking through timeline if new and popular pictures, and saw a polish fotographer, that i suppose, was making pictures in Polin. Its a museum located in Warsaw, Poland. It tells the history about Polish jews and one of the parts is about holocaust. I dont judge a picture, its great. So i want to open the topic what locations are cool for you, acceptable and forbidden?
