As i have mentioned before, we have a family business that consists of art and craft shop, picture framing workshop and gallery in which we display prints and paintings by local artists.
Sometimes, in our window display we put paintings, to catch the eye of passers by, on such painting happened to be of a group of naked women, a genuine piece of art. 
People actualy came in and made complaints that we had 'pornography' in the window. so much so we had to remove it, but it's still on show in the gallery. Does this mean we need to put a warning message at the foot of the stairs, 'Do not enter if offended by the human body?'

I think it depends on different people's comfort levels.
And also the picture itself.
If you had young kids of a certain age for example, you might not want them to see it.
And some people may genuinely find it offensive compared to others who may appreciate it.
Not just naked bodies, you could have pictures depicting violence, death, guns ... all different things, and different people would find different things acceptable.
