But you don't really need it with a PNG image... PNG is the best format. Thumbnails must still be in the thumbnail folders. Just delete all the thumbnail folders in the folder media/com_hikashop/upload and HikaShop will regenerate all your thumbnails based on the full image automatically when it needs to display it.
