Actully if you do as I originally stated it will move categories to left and image to right so try this code:

img.welcome {
float:right;
height:262px;
margin-right:220px;
width:580px;


}

Red Markup is changed, Not tested in all browsers

Alternative make the image wider then you want have to change any code to fill entire space make image say 570px that will give you, or should 5px on either side
