Personally, I'd place it as the background image within the div, the CSS for that being:
#demo {
background: url(bg_apple_little.gif) no-repeat center center;
height: 200px;
width: 200px;
}
(Assumes a div with id="demo"
as you are already specifying height
and width
adding a background
shouldn't be an issue)
Let the browser take the strain.
