summary_large_image
The Twitter Card type that shows a full-width preview image above the title — the format most links want.
summary_large_image is the value of the twitter:card tag that renders a large, full-width image with the title and description beneath it, rather than the small thumbnail of the plain summary card. It pairs with a 1200×630 og:image.
