As a rule, for Christian images we have had historical depictions from various eras and traditions, which generally do a good job of illustrating the varieties and development of such images. An obvious problem with the Islamic articles is that we need corresponding images to tell the truth about the development and variety of prohibitions against images. I personally think that the "western depictions" section of the "depictions" article could be dispensed with, but there's room for disagreement there. Otherwise the use of images of Mohammad seem relevant and helpful.
