Of course, if you're promoting affiliate links on products from amazon. The question is even where else you'll get right pictures of those products?!
You can use there pics, banners, special links, ads, whatever they allow you too that will help you sell there products. They even offer tools and widgets to help with this process, so "yes." You can. lol
Use both image links and text links in your content. I don't point my review images on the front page to Amazon, They point to the review. But sidebar images go to Amazon and Review page images point to Amazon. I don't want some one to feel duped with the front page review images.
They seem to suggest that you put their pictures on your sites, so that seems to indicate that they allow for it.
