You can create an Amazon store on their website. I was accepted a an associate/affiliate and was offered the chance to be an influencer, I applied, was accepted and they gave me a shop to fill with products I like from around Amazon.

From what little I understand Holly all digital picture have a code imbedded. I am not sure if a screenshot will eliminate that code or not.
You sure could seek the manufacturers authorization to use the image or purchase images of the products that your attempting to market from the various photo sources as an option.
Just thinking.

My understanding is that there isn't a problem if you have something in writing from the manufacturer that gives you permission to use their images. Then you have that documentation to send to Amazon if they question whether it was a screenshot or not.

But I don't remember where I read it or got the info from, so it may not be accurate! Maybe contact Amazon and see what they say about it? They may be able to let you know how they handle the situation?

Are you using your Amazon Site Stripe tool to generate your custom affiliate links? I use both the text tool, which has my affiliate embedded in the link, to hyperlink text from my review pages. I also use the Images link, which also embeds your affiliate code in the link, and use that in my review pages as well when I want a graphical representation of the product as well as a link. I usually stay away from the Text+Image option as it embeds the price, which I don't want to be responsible for updating daily on my website per Amazon Affiliate rules.

You can read a little more here about using Site Stripe - https://affiliate-program.amazon.com/help/stripe.html .

There are other Amazon product link plugins out there, but they are cumbersome to use and slow down my site. Site stripe works best for me.

Hope this helps!
