Add Social Sharing Image
Your social sharing images are displayed on social media when your site is shared. This is also the image that appears if you were to text or email someone a link to your site. You can add one image to represent your site as a whole or you can add individual images for each page.
To add a social sharing image to your site, click the gear settings icon from the Home menu and click Social Sharing under the Website tab.
Click Add a social logo and then click Upload File to add your own image from a file on your computer or Select From Library to use a file that is already in your Squarespace asset library.
Click Save to save the changes you have made to the favicon.
