I see. What you need is the image itself on a page, like this: http://ecx.images-amazon.com/images/...500_AA300_.jpg
How you get that is by a search from here: http://www.google.com/search?hl=en&q...w=1366&bih=574
That is a google image search limited to amazon.com (whose bandwidth I am comfortable using because they must make a profit from our activities here) limited to the size 300 x 300.
Without deleting the site:amazon.com part, type in what you want, like "Gesualdo madrigali" or whatever. Then click on "Full-size image." Then take that URL (the jpg) and put it between the [IMG] and [/IMG] tags.
