How to create a just plain page?

Hi everybody,

I created a site with WP. But I want to run it from the subdomain. As I plan to have many more subdomains, I want my Index page to have only logos with links (and an About Us page). (making it a static page in Reading!)

Technically, I only need a blank page without header/sidebar/footers. Everytime I create pages I am getting footers and headers. I deleted their contents, but still they have blank spaces and lines for them.

Looking at the code, I see WP putting all these calling instructions to grab them.

How do I create a blank space where I can place my images?

Looking at the Pages in Codex, I found this.
“
<?php
/*
Template Name: Snarfer
*/
?>
What follows the above five lines of code is up to you. The rest of the code you write will control how Pages that use the Snarfer Page Template will display.”

It seems this is the foundation for the page. Can I just paste my HTML after these five lines? If so, where do I put the related images?
BTW, I finished my site already. I am only stuck here.

Thanks
George
