This product shows the base features of the Attribute Image Swapper plugin. Each of the attribute option/value pairs have an associated image and provide an incrementing price.
Click on an attribute's image and it replaces the "main" product image, including its popup processing! Choose a quantity of each color and click the add-to-cart button; the shopping cart is updated with each variant of the product.
When you've added the variants to your cart, the shopping cart page shows the attribute's image instead of the product's main image!
