I don't think that it's a good idea to put these on UBBDev since this site is neither political nor religious and it must stay like this IMO.
Western culture may make fun of some religius figures, but this may not be tolerated in other cultures and in generally, even drawing "the face" of the prophet is generally forbidden (there are some miniatures that shows him with a face though, but these are so few). Some believe that this is due to prevent believers from idolizing the prophet (i.e.: making icons of him) or prevent making him equal to the God in their minds. So, this may or may not be "haram" (I'm not an authority) but the general concept is followed mostly and only a figure representing him is used without a face in old miniatures. And making fun of a religion and a prophet is another bad idea... For example, Muslims do believe in Jesus (although in a little different way then the Christianity), but don't make fun of him or the prophets before him. I recently saw a video of some sort of "Jesus Christ" singing "I'll survive" and hit buy a bus at the end (which may be found somewhere on the net). You may just laugh at that, but if you do this with another prophet name, you may start a "real" war. So, you must show respect to other people's beliefs...
And you are right that the backlash is far more greater than any other similar events. Two sides are both responsible for that and I think that there are also some other hands in these events (don't just rely on only American press since they may be misleading). But, Danish government was so ignorant and some other countries also printed these caricatures after that protests begun and this is like putting more fuel to the fire. And there are also provacateurs on the other side. And I think that most protesters didn't even see the caricatures or saw few of them. I mostly agreee with Brett on this subject...
