Sometimes the fact that a particular subject matter is distrurbing is a good reason to examine that subject matter. As long as the disturbance is not the only reason for its exsistance.
Are the photos much different than the recent (and I believe, on-going) exhibits of human bodies? A quote from the "Bodies...The Exhibition":
"These Exhibitions--which feature actual human specimens--allow people of all ages access to sights and knowledge normally reserved only for medical professionals. Take the opportunity to peer inside yourself, to better understand how your elaborate and fascinating body works, and how you can become a more informed participant in your own health care."
Though granted that the latter case the bodies are nicely cleaned up and scientificly prepared and presented.
