ギャラリーカード
このカードは2015年の7月3日に廃止され、画像付きサマリーカードに統合されました。
The Gallery Card allows you to represent collections of photos within a Tweet. This Card type is designed to let the user know that there’s more than just a single image at the URL shared, but rather a gallery of related images.
The Tweet below from @VisitCA shows a Gallery Card below the 140 characters:
You can specify up to 4 different images to show in the gallery card via the twitter:image[0-3] tags. You can also provide attribution to the photographer of the gallery by specifying the value of the twitter:creator tag.
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 Gallery Card to your tweets is as simple as adding the below meta tags to your site:
<meta name="twitter:card" content="gallery" /> <meta name="twitter:site" content="@fodorstravel" /> <meta name="twitter:creator" content="@fodorstravel" /> <meta name="twitter:title" content="America's Best Small Towns"> <meta name="twitter:description" content="For the second year in a row, we've compiled a list that highlights some of the best places in the country you don't hear about every day."> <meta name="twitter:url" content="http://www.fodors.com/news/photos/americas-best-small-towns" /> <meta name="twitter:image0" content="http://www.fodors.com/ee/files/slideshows/telluride-resized.jpg"> <meta name="twitter:image1" content="http://www.fodors.com/ee/files/slideshows/shutterstock_18216130-resized.jpg"> <meta name="twitter:image2" content="http://www.fodors.com/ee/files/slideshows/3-marfa-texas.jpg"> <meta name="twitter:image3" content="http://www.fodors.com/ee/files/slideshows/4-paia-maui-hawaii.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.
