PageView is a plugin that will display another web page inside the current post. This is achieved with the use of an 
iframe – an HTML tag that allows a webpage to be displayed inline with the current page.
To use:
<pre><code>[pageview url="http://urbangiraffe.com"]
</code></pre>
Optional arguments:
title = A title to show under the iframe 
desc = A description to show under the iframe 
width = Width of iframe, in px or % 
height = Height of iframe, in px or %
<h3>Documentation</h3>
