[Old UI] Display secondary Cross Sell image on hover

Have the second media/product image shown on your Cross Sells when hovered. To activate this feature, you will need to go to Settings > Theme and scroll down to Show / Hide product details, look for the option "Secondary image on hover", check the box and click save. 

Just like that! Now your customers will see the second image assigned to your product, when they hover over your Cross Sells! This feature can be used to give your customers another view of the product before clicking on the Cross Sell.
