You can do this using some creative CSS. The code below will allow you to grab just a part of a target page to show in an iframe. You will need to drop the iframe module and use the html module instead with this code inserted:

<style>
    #outerdiv
    {
    width:446px;
    height:246px;
    overflow:hidden;
    position:relative;
    }
    #inneriframe
    {
    position:absolute;
    top:-412px;
    left:-318px;
    width:1280px;
    height:1200px;
    }
</style>
<div id="outerdiv">
</div>

The outerframe width and height are for the part of the page you want to show.  Top and left are the positions of where you want the page to start showing and the innerframe width and height are the size of the target page if it were in a regular browser. i.e. Total size of the page.

Thanks Greg, but would you happen to know if it is possible to have the frame as a read only, that is if there is a link shown, users cannot click this???
