Unless it's a review on something new an unusual, I would think most of the reader know what a "R7 Quad" looks like. If the review is on a new product, a link to the website would provide a picture of the product I would think. Ask the reviewer for the link on any new items as part of the review form. Last I checked, you already have a place on this site with links to most of the OEM's, so that should cover most of the reviews.
