Found it in another post. For anyone with this problem you have to find your woocommerce.css file and change the image size from 48% to 20-25%. You using the find tool in your brewer (usually Ctrl+F or Cmd+F):
related ul.products li.product,.related ul li.product,.upsells.products ul.products li.product,.upsells.products ul li.product
You'll see 48%. Change it then save it. You can also change the size of the main product image by looking for:
col2-set .col-1
This will be at the top of the code and is also set to 48%. I used 25% and it worked fine.
