Header Image Showing up in social media

Excellent video tutorial. Learned a lot. There is a header media ‘suggested’ image (a man sitting with a note book) that shows up when I share my webpage link in the social media. How do I remove this image and use my own to show up when I share this web page? The Image I am taking about is seen here --> Appearance --> Customize --> Header Area --> Header Media --> Suggested.
