How can I resize variant images in the Brooklyn theme?

I previously posted this problem but no one could help me because I stupidly forgot to post the URL and password.

I am using the Brooklyn theme.  I just uploaded products and the variant sizes below the main image are all the size of the main image.  I have used this theme for another store and all the variant images below the main image are smaller and switch into the main image when they are chosen from the drop down menu.  However in my current store there is just this long column of large images.  How do I get them to be smaller than the main photo?

One of the product pages: Cat Mom iPhone Case – Gypsy Paws (gypsy-paws.com)

Thanks!

Also, the variant images are not clickable.

Never Mind.  I got it.  It was a change on the products default page
