Checking out OxyUltimate Woopack
This is supposed to solve the issue where thumbnails on the single product page turn into a slider the way it should out of the box. However, notice that it’s a buggy plugin. Click on the thumbnails on their demo product and you will notice that the main product image doesn’t change right away. You will find yourself clicking 2-3 times on the same thumbnail image for the product image to update.
That is why I don’t like using third party Oxygen Plugins.
