Here's a book that has some pictures and information on that (and other horrifying incidents) that you might find at your local bookstore:
The Rape of Nanking: The Forgotten Holocaust of World War II by Iris Chang.
Japanese military personnel practicing on Chinese prisoners/civilians during the occupation of Nanking, China. This book is not for the faint of heart.
