How to set default OG (Opengraph) image for website?

When people click to share the url to my site it creates a post with my favicon as the post image. That obviously looks crazy, so people abort sharing at that point.

How can I set a different default image for the whole site?

I usually do this in MathRank but I don’t want to install an SEO plugin on this site.

Thanks in advance.

Hi Nicolai,
You can add it either on a per page/template basis in Page Settings » Social media, or add the meta tag manually in Bricks » Settings » Custom Code » Header Scripts, so it applies to every page:

<meta property="og:image" content="https://yourImageUrl">
