The pic in the review is.. well actually pretty primitive.

Determine the ID # for the site, and create a graphic, really any graphic, but traditionally it would be a screen shot of the website. Scale the pic down to roughly 250px wide, and save it as ID#.jpg eg; for site ID # 117 you would name the graphic 117.jpg

Make a mental note of the whatever width you use.. varing the width on numerous images.. well just looks kinda tacky IMHO

Finally upload the graphic to /images/featured/ directory.

Note the graphic is only used if the featured site also has a review, and that review has been approved form the admin panel
