Genesis Add Logo Image to Header

background: url(images/logo.png) no-repeat left top;

You might need to adjust the title-area rule to match the width and height of your logo image. See the example below.

#title-area {
	font-family: 'PT Sans', sans-serif;
	font-weight: 700;
	float: left;
	padding: 16px 0;
	padding: 0;
	width: 291px;
	height: 83px;
	background: url(images/logo.png) no-repeat left top;
	margin: 5px 0 0 15px;
}
