This regex extracts the image URL from an Open Graph `og:image` meta tag in HTML. It uses a lookahead to find lines containing `property="og:image"` and captures the value of the `content` attribute into a named group called `content`. It is useful for scraping or parsing web pages to find social media preview images.
