Greene, all of the author's images are copyrighted so I wouldn't take screen shots of them, either. She writes in her blog to ask her for permission if you're going to reuse or repost her images.
Btw, on
http://hayefield.com, she has links to a book giveaway. Her book isn't coming out until next month but she previews some of the pictures in her blog. Wow, she's an awesome photographer!
