Notice I linked to that above. Which part of it prohibits linking to images, or reselling items? Linking to a long document and claiming it says something isn't helpful. Excerpt the parts you think support your claim.
Read "LICENSE AND ACCESS" and the rest of it too. Is there a particular reason why you adopted Vlad's strategy of posting without reading? Is there a particular reason why you expect me to do your homework?
I read through most of the document, and saw that it doesn't clearly prohibit what coinstand is doing. (It depends, as I said above, on whether images count as software, which seems unlikely).
You made a claim that what they are doing violates the TOS. The burden of proof is on you, so don't try to get out of that by just telling me to read a document that doesn't actually support you.
Subject to your compliance with these Conditions of Use and your payment of any applicable fees, Amazon or its content providers grant you a limited, non-exclusive, non-transferable, non-sublicensable license to access and make personal and non-commercial use of the Amazon Services. This license does not include any resale or commercial use of any Amazon Service, or its contents; any collection and use of any product listings, descriptions, or prices; any derivative use of any Amazon Service or its contents; any downloading or copying of account information for the benefit of another merchant; or any use of data mining, robots, or similar data gathering and extraction tools
The two questions here would be whether the "lack of license" implies that embedding is outlawed, and whether the images count as "proprietary".
That is, the part you quoted amount to saying "we aren't giving you the right to copy this", but they aren't directly saying "copying this is against the terms". They aren't claiming new rights, only saying that they aren't giving up their old rights. So the question would become whether they had the rights on embedded images in the first place.
In particular, the statement "or other proprietary information" may not include images of products.
But this is already lawyer territory, speculating probably wouldn't help.
