I wasn't implying you were stupid. Users get their paths wrong all the time.

This is what you have in your css for the page:

.tcat
{
	background: #000000;
	color: #ffc741;
	font: bold 10pt verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif;
	.customback { 
		background-image: url('http://i25.tinypic.com/2rxcx86.gif');
	}
}

You have .customback nested within another class declaration. That isn't going to work. End the previous declaration, then declare yours.
