Blog post from Google yesterday. I've highlighted the important bits.
I've heard the use unique images argument before but it's a hard one to quantify. Reviews with unique images rank better but reviews with unique images are generally better quality reviews than your standard run-of-the-mill Amazon affiliate sites. I've switched to using them on some of my newer review sites but it's hard to say what they actually look for.
As for including multiple sellers - maybe throw a link to the vendor somewhere down the page and see what that does. If it ever actually becomes a meaningful ranking factor, set up a dropshipping site with a higher price tag and ship the product from Amazon anyway.
TL;DR: Use unique images and links to multiple sellers, not just Amazon.
