Your visitors may submit pages from your web site to Digg. When they do, we will try to fetch a thumbnail to associate with the submission. If errors occur or we don't get the thumbnail for any reason, it's no problem; we'll just display your item on Digg without the thumbnail. Thumbnails are fetched during submission of the URL to Digg, so they should appear immediately on the site.
We’ve implemented Facebook’s “share” standard for enabling thumbnails on Digg, which means that if you correctly implement the standard below, your thumbnails should appear on both sites when submitting video, news, and image stories.
To ensure that your thumbnail is properly displayed, you should add the tags shown below to your html. An example news article, video, or image could have the following:
<meta name="title" content="Remembering Evel Knievel" />As shown, title contains the story title, description contains the story description and image_src contains the thumbnail image. Please make sure that none of the content fields contain any html markup because it will be stripped out. For consistency's sake, please use the <meta> tag to provide text data for the preview, and the <link> tag for any source urls.
The title and summary tags are the minimum requirements for any preview, so make sure to include these two.
You may also specify the type of content being shared by using the following tag:
<meta name="medium" content="medium_type" />
Valid values for medium_type are "audio", "image", "video", "news", "blog" and "mult".
Methods that have previously worked on Digg will continue to do so, though we encourage you to switch to the method above when possible.
Note that this is an option ONLY for those directly hosting videos submitted to Digg. If your video is embedded on your page but hosted elsewhere (e.g. YouTube or Google Video), and your videos do not already include thumbnails, please ask the hosting site to visit this page.
