>From what I've seen of how it works, I believe they use JavaScript to swap the image in and out. That might affect why it doesn't print with that; I don't know: however, I don't know how it doesn't show up when you "view image". ...Of course, if they're using CSS to achieve layers, then they might be putting the transparent pixel image in /front/ of the real image, meaning that when you right-click on it, you're actually right-clicking on the transparent pixel instead of the one you see. And I think the printing stuff doesn't handle transparency, so that would make some sense, too. > Is there a way of saving the book page > contents to an image file?

For more, you may have to dig around quite a bit to check out the JavaScript, and any interactions with the server. Probably not worth the hassle. -- Micah J.
