+Simply add the `frame-tilt` CSS class to an image, i.e.:
+
+    ![alt text](myimage.jpg?classes=frame-tilt)
+
+or
+
+    <img src='mypage/myimage.jpg' class='frame-tilt'>

+		// Create photoImages with a seed-based rotation
+		jQuery('.my-frame-tilt').photoImages({
+		    boxShadowOffsetX: '10px',
+		    boxShadowOffsetY: '10px',
+		    boxShadowLength: '10px',
+		    boxShadowColor: '#7f7f7f',
+		    marginRight: '10px',
+		    rotate: 'seed'
+		});
+	    });
