How to group your product images as thumbnails in Brooklyn theme?
If you have lots of product images and the app widget is placed at the bottom of the page, it is possible that the widget may not be seen by most of your customers.
If you want to make it more visible, you can group the product images together as thumbnails, instead of having them stacked one above each other.
To group your product images, please go to your Shopify Admin, and in the Themes section, please click on Customize:
Once there, please select the Product pages section in the banner at the top:
And then, please select again the Product pages option in the menu at the left:
After that you will find the option to select the Image display, from where you can select the option Thumbnails. Select it, click on Save on the top right corner and you will be all set.
