Here you can find a handy guide to the options available for Product Page Galleries:
Gallery style: lets you choose how you want your images to appear as 'Grid' or 'Stacked', 'Carousel' or 'Mosaic'
Theme: choose between a 'Dark' or 'Light' coloured background for your lightbox view
Rows/Columns: allow you to change the number of rows and columns
Gutter width: manage the space between your images
Outer margin: let you set the outer margins of the embed widget
Rounded corners: you can opt to have rounded corners ‘yes’ or select ‘no’ if you want image corners to be straight
Optimise display by: let you choose if you want to optimise your images by ‘most engaging posts’ (calculated by most viewed and clicked posts) or by 'most recent posts' or by 'most likely to sell' (based on the tracked conversion code we can display images that sold the most)
Embed heading: use this space with a catchy ‘#’ like #showyourstyle #howtostyle or with a call to action like 'Show us what you’re loving and how you are wearing it,'
Style/Position: allows you to change your heading style and position
