They're just photos, and nothing we haven't seen already. Exploring the interior of the ship is where it gets trickier, but more rewarding. I think one expedition knocked over the crows nest or something.
But if anyone saw Ghosts of the Abyss, James Cameron's crew was able to get in the cargo hold and photograph that Renault, which I thought was pretty extraordinary. Wikipedia lists some of the known damages since its discovery, which, come on now idiots, watch where you're going.
In a barely related story, one of my favorite parts of the Royal Ontario Museum was a turtle shell that someone had accidentally dropped and broken, which allowed them to discover preserved eggs inside. It's the only example of this in the world. Not that we should go throwing around artifacts, I just loved how that particular situation was able to resolve itself.
