Yup,
ASIN code for books corresponds generally to ISBN-10. At least, when Amazon gives me the affiliate links it's the way it works.
I tried to insert an image only after reading your message and it went fine.
In fact, you'll have to copy/paste the "image only" HTML code as I can't guess the image source only from that code bit.
For example, I copy/pasted that:
<a href="http://www.amazon.fr/gp/product/0441017150?ie=UTF8&tag=onctom-21&linkCode=as2&camp=1642&creative=19458&creativeASIN=0441017150"><img border="0" src="51FTO0Y-nnL._SL160_.jpg"></a><img src="http://www.assoc-amazon.fr/e/ir?t=onctom-21&l=as2&o=8&a=0441017150" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" />
I "apply the magic" and then, it autoconfigures the widget, I insert it as this shortcode:
[amazon-product image="51FTO0Y-nnL._SL160_.jpg" type="image"]0441017150[/amazon-product]
Try and tell me :-)
