A note on copyright, written all over photos. There's two possible reasons to do this: (i) you're totally paranoid that someone is going to use your hard won images for their own personal gain, and you can't stand the idea of that, or (ii) you're totally too egotistical and think that anyone gives a care to steal your images and use them badly. Given the subject line, perhaps you've self selected for option (ii), in which case just go over to photoSIG and check out the over 20,000 images in the category "erotic," and notice how many of *those* images have a copyright slapped on the model's chest. The other comments about the image are most appropriate.
cheers,
