I'm ambivalent on this particular issue. On one hand, the content doesn't convey direct information on Muhammad and is therefore not essential to the article. Consensus matters, and clearly there isn't consensus on including this image, and so it should be out. On the other hand, I'm strongly offended by the view of some Muslim editors here that Wikipedia should in any way adjust its presentation to be "Islamic". While Islamic law may prohibit Muslims from depicting Muhammad, non-Muslims shouldn't be pressed to follow Islamic customs. Naturality in the spirit of civility, even non-Muslims shouldn't engage in presenting works or content that denegrate Muslims or Islamic customs. This image however does not seem to be intended to denegrate Muhammad or Islam in any way, and therefore it's unreasonable for Muslims here to be so agitated by such images. The image shouldn't be included, in the end, since there isn't consensus. I'm not happy with the idea of giving into fundementalist muslim mentality though.
