If you’re embedding a Gallery using a Theme with a Share button enabled, it will be possible to share your Gallery on social media sites. You can adjust these settings on the Share Button page in the Themes section.
Similarly to when you share a SmartFrame image on social media, only a small thumbnail, title and/or description will be visible in your post. The thumbnail will always be the first image in the Gallery and title and description are automatically generated from the Gallery title and Gallery description. You can edit these in the Overview page within the Gallery.
