How install a background image?

[rjouglard]

I am trying to install a background image to cutomize my website. I got it to work one time and after I modified my image, I couldn't get it to work anymore. The images folder I am using is the main image folder under my domain. Here is what I have in my classic/stylesheet.css
body {
margin: 0;
font-family: verdana, arial, helvetica, sans-serif;
font-size: 62.5%;
color: #000000;
background-color: #B5EAAA;
background-image: ../images/bkd.jpg;
background-position: right;
}
