Hi mjdavid007,
Thanks for reaching to us and appreciate your patience.
1. Please make sure you added galleries images to the products.
2. You are using Custom WooCommerce Builder layouts, which is part of WooCommerce Builder from WoodMart. Navigate to Layouts > Edit Single Product Layout > select Product gallery
widget and change the layout.
Further, you can read more about the Layout Builder here: https://xtemos.com/docs-topic/woodmart-woocommerce-layout-builder/
3. Or you can go to Theme Settings > Single Product > Gallery and here you can change the thumbnails layout.
Regards,
