What featured image is

A featured image is an image that shows all variants of a product. For instance, if you are selling a T-shirt with a lot of different colors, then the featured image in this case will show all color variants in one picture. The featured image would inform customers about how many variants a specific item has, hence they will quickly make their decision to choose the variant they like.
