Add product variants

Add variant images to a product that has more than one option, such as size or color
A combination of option values for a product can be a variant of that product.
If you haven’t already, start by adding product variants and their corresponding variant images.
From your Shopify product editor, go to Variants > click on the image icon on the left > Add variant image.
Each product variant takes one variant image as shown below.

In default Shopify admin, you can only choose images as variant media. The product images should all be the same ratio and dimension to streamline your product showcase.
