Change product image on change selecting color
On the demosite http://demo.commerceguys.com/dc/catalog/coffee-holders/mug when changing color the image is changing also, how is this possible?
I have made 4 products with different images and give each product an option from a selectlist.
In product display I made an product reference option as selectlist where I can select which color is displayed but when select something nothing is changing.
Someone an idea??
