This plugin will add a noembed section no any embedded content that does not already have one. This is very handy for people reading your site in an RSS reader, as a lot of them don’t display embedded content.
Also, for any Youtube or GameVideos.com videos, this plugin will also show a thumbnail of the video. The message displayed can be customised from the options page for the plugin.
See the Plugin Homepage for more information.
