The thumbnail images in the shopping cart give customers a quick overview of the items they are about to purchase. However, for products with multiple options, the standard product image may not match the actual item being purchased. If the customer purchased a pair of red shoes, ideally, the thumbnail in the shopping cart should show the product in the same color.
The thumbnail image for both grouped and configurable products can be set to display the image from either the “parent” or associated product. The setting applies to all grouped or configurable products in the current store view.
