The Summary Card can be used for many kinds of web content, from blog posts and news articles, to products and restaurants. It is designed to give the reader a preview of the content before clicking through to your website.
The Tweet below from the United Nations (@UN) shows a Summary Card (photo and text) below the 140 characters:

Sample Code
Adding a Summary Card to your tweets is as simple as adding the below meta tags to your site:
<meta property="twitter:card" content="summary" />
<meta property="twitter:site" content="@flickr" />
<meta property="twitter:title" content="Small Island Developing States Photo Submission" />
<meta property="twitter:description" content="View the album on Flickr." />
<meta property="twitter:image" content="https://farm6.staticflickr.com/5510/14338202952_93595258ff_z.jpg" />
<meta property="twitter:url" content="https://www.flickr.com/photos/unicphoto/sets/72157645001703785/" />
Be sure to provide your own site attribution and content.
Once the tags are live, you can submit your Card for approval using our Twitter Card Validator.
