Not really working for me. I've done a console log inside the select change function, but it doesn't seem to be running. any ideas?

I am trying to get this to work on the Shopify theme Canopy. I have not been able to get it to work, but the product.liquid code is a bit different from what I see here. My code skills are not good enough to modify this for my theme. Could I send you the product.liquid file and have you alter it to make it work?

gistfile2.html works. It will only display the images assigned to the same alt tag.

gistfile1.html however, is not fading in or swapping out the thumbnails at the bottom, only if you refresh the page you see the thumbs assigned.

Any advice on this?

This code not work in product.liquid so please help me.
