After further testing, I have got the attribute images working correctly on the homepage, category page but not on the product page, it displays the attributes as a drop down box.

When I edit the Attribute Terms and tick the box titled “Enable Swatch” it makes the attributes display as a thumbnail but stops displaying the thumbnails on the homepage and category page (it displays the attribute name as text).

This seems to be a bug, are you able to review and help me fix this?
