I believe I have something for you that might suit your needs. I went ahead and managed to do this on my own test store.
<div class="grid__item large--seven-twelfths medium--seven-twelfths text-center">
For me this code is on line 11
Push everything down one line and paste the following code just below that line of code.
Make sure you have a URL to your qulity guranteed image and replace the one that I have in the above code: <img src="https://YourURLhere.com">;. Reminder, you can upload files in Settings > Files and use that URL we give you there.
And now on all of your product pages, you should see your image appearing above the product photos in your Brooklyn theme. Here's what it ended up looking like: https://screenshot.click/04-22-qnmmh-mw5m6.jpg
Hope that helps!
