It seems that most of the photos available of the Bismarck wreck are 'private property'... The stuff available on the net is typically a 'computer rendering' from the photos that we are not allowed to see.. The site that seems to have the largest number of real photos is the site put up by the H.M.S. Hood Association here..
The photos are posted with this notice:
