I posted a link to this gallery in another thread in the Rivet Review Forum and it seems not everyone knew about it. It's the official Navy News Gallery and it contains over 8000 images of Navy related pictures-many of which are very, very hi-res which makes them good for detail references. There's a search function as well which is handy. Anyway, here's the link:

Thank you, that is a great link. I got a lot of marine models, and this
site definitely helps :-)
