Personally: why delete the image? Do we delete images of sexual organs, 'cause "offensive"? It doesn't seem so.
Don't you think that there is a slight difference between body parts and personal attacks to a politician? Or do you see any violation of NPOV in pictures of genitalia? At least I don't...
I think the only possible place to use these images is in articles about these kind of images or about the painter or the publisher of such things.
