Amazon affiliate picture link

If I have an article on a blog describing 5 products and the 5 pictures of the products link to the product on Amazon is this allowed in their Tos? The Pictures don't have text like buy now on Amazon or anything. This way I think they will click on the pictures to maybe see them better and go to Amazon. In the text I will also provide a link that says buy this product on Amazon.
I can't find anything about this on Amazon is it allowed?

Interested in answer of this.
I am doing the same and getting sales. Haven't thought yet if it's allowed or not.

I believe it is possible. I've been doing that and there hasn't been any problems in my side. Been doing it for years

Thanks for the advice do you get your traffic from seo or social media? And is ppc allowed (facebook adds) or not profitable ? Im new to Amazon

I get traffic from SEO for my amazon sites. I'm positive that PPC is allowed if you're directing them to your site and they click the link and go to the amazon product. But a direct link to amazon product is something I haven't tried
