Here is an easy way you can hide parts of the page that you don't want others to see. All you need to know is the page element name. You can add a HTML snippet to the header and footer and it will appear on all pages in your site, or you can just add this code below your primary Text-Image element so the change only affects this page. The example below hides the page header which contains the logo and search buttons.
<style>
#header {display: none;}
</style>
You can also hide several elements with commas. Be sure to put the # sign in front of each element:
<style>
#header, #footer1, #footer2 {display:none;}
</style>
A handy tool to inspect your website is called 'Firebug' - a Mozilla firefox plug-in. To install Firebug from firefox choose 'Tools>Plug Ins>Search' and Firebug. Install it and restart your browser. You can then activate it in the bottom of the page and 'inspect' the page element name on the page.
Hiding the Main Navigation
<style>
#mainNav1,#mainNav2 {display:none;}
</style>
