I don't think it matters what was left to the imagination, it's how Barbara feels personally about being nude. I understand, and that's really her choice no matter how frustrating it is.
On a more positive note for Barbara, I understand why she'd be embarrassed and want the photo taken down, but at least she did this professionally. It's one thing to have an unpublished nude from a photoshoot floating around the internet but something else entirely if she were the victim of a hacking. I only hope that this is a mild embarrassment for her and that she can find a way to get passed it.
