Typically a skin would have the background image defined in CSS using the Body tag, though there are other ways to do it as well.

I figured out how to change the web site background using hard coded CSS as well as using the CSS for the portal. That's about the extent of my knowledge in CSS at this time. So as to identifying an ID or class i am unsure of how to accomplish this.  I was able to manipulate the website background image by placing this into the portal.css:

#Body {
background-attachment:fixed;
Background-position:center center;
background-repeat:no-repeat;
}

Now it is my understanding that the #Body is an ID reference which is handled at the website level.  The skins CSS file has a Body in it as well, but when i make changes directly to the file, i do not see any changes happen at the website.  This is where my confusion comes in.  I am an avid VB.NET applications developer, and having to deal with the multiple layers that comprises a website is definitely a long way from home for me!
