With the new style categories the product pictures are larger, since the changes came in on the wedding category I have noticed a 50% increase in favourites vs views. I believe this comes from people no longer needing to click through to your product to see a large clear picture.
Very interesting on the style categories. I don't shop that way, so I had no idea the photos are that much larger. I can't tell if that's a good thing or a bad thing, though, that they don't click on the image.
