<p>Multisite Featured Image changes the box of the featured image for all sites. It can be used also in a single instance of WordPress and not a MU installation.</p>
<p>This plugin changes the box in the way that the default pop-up is replaced with the classic Media Uploader where you can choose images. <em>Images From URL do work</em>.</p>
<p>For a greater Multisite experience you can combine this plugin with the <a href="https://wordpress.org/plugins/network-shared-media/" rel="ugc">Network Shared Media plugin</a> and have a complete Media Sharing site.</p>
<p>Read about it on this <a href="http://siderrz.com/wordpress-multisite-shared-featured-image/" rel="nofollow ugc">article</a>.</p>

<p>This plugin does one thing, and that thing is to add your posts’ featured image to the RSS feed. It specifies the ‘large’ image size.</p>
<h3>Open Graph Meta Tags are also Necessary</h3>
<p>Many modern feed readers do not show the images added by this plugin. Feedly, for example, will not show images added by this plugin. Feed readers crawl article pages to find the image attached to posts in the open graph meta tag. Many SEO plugins add open graph tags for featured images. I like the (https://wordpress.org/plugins/opengraph/)[Open Graph] plugin, too.</p>


Add Featured Image to RSS Feed

Adds the featured image attached to posts to the beginning of the post content and excerpt in RSS feeds.
