Trunk Bay Wikipedia

So I checked out Trunk Bay in Wikipedia to see if my picture and I received a message, notifying me that I don't have a copyright tag on my picture. So I went into the image and added "Photographed by: Jessica Williams" although I have no idea if that's what I am supposed to do. Anyone have an idea? Here's the link: http://en.wikipedia.org/wiki/Image:Trunk_bay.jpg
