Hello, I've been reading google posts and drupal discussions for the past 48 hours and haven't found anything that will help me with what I'm sure must be an easy fix, so I'd really appreciate some help on this. I'm trying to change the background image for a specific node (node 3 to be exact). I have already changed the background image for my site by adding

body {
background-image: url("http://www.alecegan.com/sites/default/files/imagepicker/1/background10.jpg");
background-position: 50% 50%;
background-repeat: no-repeat;
background-attachment:fixed;

}
#content {
position:relative;
z-index:1;
}

to the style.css file, but I want a different background image for node 3. Can anyone suggest a way to do this? I've been reading about adding a specific reference and messing with the page.tpl.php file as well, but have had no success in all the posts and modifications I've read. My site is www.alecegan.com, please check out the code, I'd appreciate any advice. Also, I noticed that this theme has no template.php, is there a reason for this? Thanks!!
