This is the trick IMDB uses for actor and still photos. The overt "image" is a clear gif overlay. The actual image is a CSS background, which you can still access/manipulate by viewing source. Not sure what Amazon's trick is, but view source should provide a clue. > > Is there a way of saving the book page > > contents to an image file?

Note that what you get then is a bitmap rather than the source image format, which may have better scaling capabilities. Peace. -- Karsten M.
