I have exactly the same problem as tdc666, so if there has any solution been found yet, I would appreciate it if you tell me.
My customer sells wool, each in different colours.
Each combinations shows the associated images.
The default combination shows ALL images, i.e. someone clicks the yellow image, the yellow wool is displayed.
If he clicks add to cart, under the impression to buy the yellow wool, he in fact buys the (default) purple one.
