Your example is working fine on my site too.
By using your example:
I get the following link:
<img src="http://ecx.images-amazon.com/images/I/51lQO2My%2BmL._SL160_.jpg" border="0" width="" height="160" alt="James Patterson Lot of 6 Books, 1, 3-7 a Womans Murder Club Novel. (A womans Murder Club Novel)" name="image" align="left">
As soon I use one of my own books I have the problem "Book not found!!!!!", even when I either the book information on my own or fetch it from amazon.com.
My Joomla-admin pages tell me, that there is a new version: Message Available new version Booklibrary 3.6.10 Pro ,creation date November 2016. As I have bought my version on november 10th, I would like to know, if I'm entitled to this new version?
Thanks for your help.
