Here's a good test to determine if the images are sacred.
Simply SUGGEST them being removed. (stand back and be prepared to be marginalized at least, castigated or worse most likely)
This is interesting. My mother-in-law died recently. My wife brought home several of the paintings and artwork she had in her house. Almost none of them would fit our contemporary theme or decor, but that's a side issue to this discussion.
One of them is the famous portrait of Jesus praying in the Garden of Gethsemane before the crucifixion. I asked her what she planned on doing with that painting, because I told her I'm not going to have it hung in my house. (Told her that about ALL the paintings, but again, that's not germane to this discussion.) "I don't know, but I feel weird throwing it away." (Wife is former Catholic.) I guess the tacit consensus is that it will be donated.
