Islamic Depictions of Mohammed in full

Here's a page showing dozens of paintings and depictions of Mohammed, apparently made by respectful Muslims. I haven't seen the second part of the latest South Park where images of Mohammed were supposedly censored, but as long as they were experimenting with it, it would have been interesting if they had shown a photo of one of these 700 year old paintings of Mohammed. Of course the voice-over or the context of Mohammed around the other characters could still be seen as disrespectful, but how angry can you get at these cartoonists for simply rebroadcasting images that are fairly common (because not all Muslims forbid depictions of Mohammed)? If "zombietime.com" can be trusted, they claim that some of these images or similar ones are displayed in multiple museums around the US.
