Social media sites often use the image_src microformat for displaying link thumbnails. This simple plugin adds the image_src rel value to the code of your site. By default, the plugin applies only to singular views and it uses the featured image. It only applies when an image is available. The '@image_src' filter hook allows for image customization and/or extending the plugin to other views.
