Just as QantasA332 and Jaspike said, if you just select "correct info" on your photo, change what you want changed and cite the reason for change in the appropriate block, they'll happily accommodate the change. I've done it to a few of my photos myself. They're really good about that.
I have a really bad habit of reiterating what people have already said...sorry guys.
