Embed the Product Gallery Code
The Product Gallery Embed Code is the same for every Gallery:
That's the same Embed Code you use for individual Galleries but without the specific data-id for that Gallery.
Paste that code in your product template anywhere you would like to see your Gallery. If you're using a sectioned-based theme paste the code in the product section.
Look for a file named product-template.liquid or similar. If you are unsure where to paste it contact us or your theme developer.
