Variation swatches not changing product image on product list page

Hi there! I almost have this thing working! I am using the image swatch profile. The images come up nicely on the product list pages, but when you select one of the swatches, it does not change the main image. On the single product page it works well, but on the product list pages the tool tip works, the swatch changes size when you select it, but the main image does not change. I think this will be confusing to customers as they will see that the swatch was selected, but nothing happens. They may think the site is bad. Please advise.

Thank you!
