When adding a product image or video, the first item is the featured image of the product and it is shown on the home page, the collection pages, the cart page, and the checkout page.
For some products adding a video could help shoppers decide to buy the product. A video is useful for explaining complicated or technical products, introducing customers to innovative products, or showing the use of a product.
