#portraitframe {
margin-top: 20px;
margin-bottom: 20px;
width: 350px;
height: 363px;
background-image: url({PortraitURL-128}); }


#portraitframe .overlay {
margin: 0;
width: 128px;
height: 128px;
background: url('http://static.tumblr.com/l7hwqgf/paOl9hktd/portraitframe.png'') top left no-repeat; }
