Hello,
Change product image on attribute clickâ allows you to display different product images based on the selected product variation or attribute.
Navigate to Products > Attributes > edit Attributes and enable the option Change product image on attribute click.
Enable the Additional variations images option in Theme Settings > Shop > Variable products: https://take.ms/aRzS2 and upload and appropriate images to the variations: https://take.ms/MiDHc Then the images will change by clicking on the swatches.
For the product grid attribute, You need to select your attribute in Theme Settings > Shop > Variable products -> Grid swatch attribute to display.
Best Regards.
