This app solves the problem of being able to display Amazon product images without violating their TOS. It does a great job of finding the images from either keywords or an ASIN number and the button to add images is prominent displayed when creating a new post.

I know some have complained about the fact that it drops the image at the bottom of the post and then you have to drag it up. I found a solution to that. Just drop the image at the bottom of the post then click the image block, click copy, delete the bottom block and then paste it into where you want the image to appear. This app is already generating more clicks on my sites and some sales and I only bought it about a week ago.
