Summary Card with Large Image

The Summary Card with Large Image features a large, full-width prominent image alongside a tweet. It is designed to give the reader a rich photo experience, and clicking on the image brings the user to your website.

The Tweet below from @NatGeo shows a Summary Card with Large Image along with the 140 characters:

Our system recognizes when URLs are included in a Tweet, and crawls your site to fetch the Card type and content. To learn more about how our Card system works, read our Getting Started Guide.

Sample Code

Adding a Summary Card with Large Image to your Tweets is as simple as adding the below meta tags to your site:

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@nytimes">
<meta name="twitter:creator" content="@SarahMaslinNir">
<meta name="twitter:title" content="Parade of Fans for Houston’s Funeral">
<meta name="twitter:description" content="NEWARK - The guest list and parade of limousines with celebrities emerging from them seemed more suited to a red carpet event in Hollywood or New York than than a gritty stretch of Sussex Avenue near the former site of the James M. Baxter Terrace public housing project here.">
<meta name="twitter:image" content="http://graphics8.nytimes.com/images/2012/02/19/us/19whitney-span/19whitney-span-articleLarge.jpg">

Be sure to provide your own site attribution and content.

Once the tags are live, you can test your Card using our Twitter Card Validator.
