OG images are the category developers usually reach for first, because the alternative is running a headless browser to screenshot an HTML page — a rendering stack to deploy, keep warm and debug, purely to produce a 1200×630 PNG. A template with the title, author and tag as variables does the same job with one HTTP request and no browser anywhere. Sites generate these at build time, one per post, or on publish so the image exists before the URL is first shared. The title field is the one that needs care: post titles vary from four words to twenty, so auto-fit rather than a fixed size is what stops the long ones overflowing.
In practice: An API call from the build pipeline or the publish hook, taking back a hosted URL to put in the og:image tag.
