Product image not changing on select

I am populating a store with the clients products. One of the products has several different sizes associated with it and a different image for each.

products_detail.php?ProductID=36

In this case there are 4 options and the picture should change when going through the selections but it doesn't.

I created the drop down using the advaced options because the price changes for each selection also, I uploaded an image for each selection but it is not changing as I assume it should.

Have done something wrong? Everything else with this product works.

Thanks for the help.
