Its a nice site, but it has some flaws;

Thats a painting...

and thats not a battleship, its Adm Hipper or possibly Blücher, forgot wich.
Some photos are photoshopped to colour afterwards aswell, they were originaly black and white. Pretty fun, and easy, thing to do actually.
But lets not complain, eh.
