When your visitor clicks on a thumbnail, a modal showing the full image along with the username, social sharing, captions, and products will be shown. Visitors can pin photos into their pinboard--further expanding your reach and building your brand.
When the visitor decides to pin the image, it will take them through Pinterest's pin flow.
Your photo will be on the visitor's board where it can be further seen and shared by others.
When a photo is clicked, it takes them to your store with that modal of that photo opened. This helps to expand your reach and further build your brand.
