Product media
Product media can include images, 3D models, and videos. Using media like 3D models for your products provides your customer with a better understanding of the function and size of an item, and increases your customers' confidence in the quality of your products.
You can add product media directly to your product pages, or by using metafields. If you have an Online Store 2.0 theme, such as Dawn, the free Shopify theme, then you can add references to your product metafields through the theme editor.
You can also access product media and other files by navigating to Content > Files within the Shopify admin. You can filter your list of files using the Used in search dropdown and selecting Product media. The Files section of the admin allows you to view all your files used across every product in your store.
