With regard to Amazon, they used to allow downloading images and uploading them to your site. Now they don't. But most of the product images, excluding those uploaded by customers, belong to the manufacturers - Amazon does not have copyright to them, and they can't prove you downloaded them from their site. How can they penalise everyone? But I think to be on the safe side from now on, it is best to comply with their rules going forward. This is what they say in their FAQ: "Can I copy the images/reviews/logo/videos from Amazon.com to my website? We don’t allow you to simply copy and paste directly from the Amazon.com website. You are welcome to use the linking tools available to you in Associates Central which provide images that are linked directly to Amazon.com. " Link: affiliate-program.amazon.com/help/topic/t64/a2
