<p>Embeds are needed to embed video from youtube or to embed Google Map or just to embed content from external page.<br />
WordPress removes embed when you switch from “HTML” to “Visual” tab because of the security reasons.<br />
So you can embed object code using this shortcode <code>[iframe src="http://player.vimeo.com/video/3261363" width="100%" height="480"]</code>.</p>
