This thread is resolved. Here is a description of the problem and solution.
Problem: My product gallery images do not show in the secondary language.
Solution: I found that in the secondary language, the images have different titles and they were all throwing 404 not found errors in the browser console. I went to WooCommerce -> WooCommerce Multilingual and changed the settings to edit the product using the native WordPress editor. I then uploaded a copy of the image that I made from the DE product. Now you can see that the image zoom is working correctly on the English translation.
