* Category Search: Browse through the top-level category that your item is in (eg: Clothing). Does your item "jump out" at you? What photos catch your eye? What sorts of colors, angles, and shots make you want to click? Which types of photos have the most views? (keep in mind that some items with an astronomical view count may have been renewed, or may be featured in blogs or treasuries.)
