Stumbled upon a website that explains the syntax needed to pull images from Amazon…with nothing more than an ISBN number (for a book, anyway):

Should be able to write a routine in the OPAC to pull in these images based on isbn number. Of course, Amazon might take exception to the server drain…maybe you could code the image to deliver the “clicker” to Amazon’s doorstep for a purchase…be sure to sign up for the associate’s program before you implement that.
Here’s a URL for a thumbnail image of a book with this isbn: 0-7645-4716-X
http://images.amazon.com/images/P/076454716X.01.THUMBZZZ
does it work?
If you’re looking at a thumbnail of PHP4 bible, then it’s working. Just remember to omit the dashes in the ISBN.
