The above code snippets address the display of the average rating, number of reviews and sellers. The graphic ratings display is a selection from a series of star images. The RateImage function rounds the average rating to the nearest 0.5 and assigns a corresponding image source url for the IMG element. All the anchors for this section point to the main item page on Amazon, however, a little additional research may uncover whether there is a separate url for a ratings, review and seller list.
