I would like to know if there were a way that I could use a simple image as a border for my ENTIRE web page, not just a table or anything. Meaning the image would be around all four sides of my webpage.

body {
background: (your image here);
color: #000000;
margin: 0;
padding: 0;
}
div#page-container {
margin: 10px;
padding: 0;
background-color: #FFFFFF;
color: inherit;
}
That will effectively create a 10-pixel border minimum around your entire page. You may notice more of a border in the footer on short pages.
