Use a little Css to hide stuff in an iframe.

I got this from http://blog.scyberia.org/ - many thanks!

First, create a container for the iFrame which covers up certain part of it. 

#iframeholder {
   width:700px;
   height:700px;
   overflow-x:hidden;
   overflow-y:auto;
   position:relative;
}

Then create an ID for the iFrame:

#inneriframe {
   top:-100px;
   left:-200px;
   width:1280px;
   height:1200px;
   position:absolute;
}

Then, the html:

<div id="iframeholder">
<iframe id="inneriframe" src="http://example.com/"></iframe>
</div>
