You can use the "Selected Dynamic Item" to configure a product images carousel to automatically scroll to a variant's featured image when the variant is selected. To do this:

1. Ensure you have a product images carousel and a variant list component set up inside a product box (see Products for more info)
2. Go to the Config tab for the carousel and find the "Selected Dynamic Item" configuration value
3. Via the Dynamic Data modal choose Selected Variant > Featured Image
