I followed the FAQ, bascially copy and pasted the code, double checked to make sure that everything was uploaded properly and I still get nothing

In the CSS file I edited this;
Code:
#mainWrapper {
	background-color: #674068;
        background-image:url(../images/main.png);
        background-repeat: repeat;
        color: #fff;
	text-align: left;
	width: 100%;
	vertical-align: top;
	}
Everything but the background-image works fine.

The image is in /includes/templates/satinBlack/images/

satinBlack being my custom template. What am I missing here?
