The browser extension, ImageFlow for Amazon - PictureFox, makes it easy to view Amazon product photos in a gallery like Apple's CoverFlow.
After you install the extension, you'll notice a Play button above the images on the Amazon product page.
Clicking on the Play button will launch the ImageFlow gallery in a new tab, where you can easily navigate through all the photos, including those uploaded by customers (can be disabled).
When browsing through a list of Amazon products, hovering over the product will also display an enlarged preview image of that product. If you don't like this feature, you can go to the extension options and disable it. You can also disable the ImageFlow layout altogether. With the ImageFlow layout disabled, clicking on the Play button will display all the hi-res photos in a single page.
