How to Add a Social Sharing Image to a Website Page
A social sharing image—also called an Open Graph image—is the image associated with an individual website page when that page is shared on social platforms such as Facebook or LinkedIn.
You can choose a social sharing image for an individual page on your Site Before Night website, which gives you more control over how that page is represented when someone shares it. You can also use different images for different pages.
Open Manage Pages
From your website editor, open Pages and select Manage Pages. This is where you can choose the individual page whose social sharing image you want to change.
