Couldn't this whole problem be addressed simply by creating a separate article, with a title such as [[Abu Ghraib/Photos of abuse]]? The [[Abu Ghraib]] article itself could include one or two of the photos, plus a link to the separate article where the other photos appear. Presumably anyone who visits an article titled [[Abu Ghraib/Photos of abuse]] would know to expect that they will be viewing disturbing images.
