With this mod you could create different images for each option value you have, is perfect for products that have different colour option. Also when you click on add to cart the option image will be instead of product image. So if you buy a white T-shirt the customer will see the white T-shirt image for that option.

Features:
Attribute helper will help you to fill the attribute values for each product. Each time you change/insert a product attribute, the system will show you a select with all values stored on the database, so you can write a new value, or select it from the database.
Also, it will help you to fill all the attributes via an attributes group select when you create a new product.
