I link erano giusti, adesso ho questo come risultato


i codici sono questi
codice:
<div id="header">
   <div style="width:937px; float: right; margin: 20px 20px 0 0;"> 
      <div id="header_img1" ></div>
      <div id="header_img2" ></div>
   </div>
</div>
codice:
#header {
height: 91px;
background-color: #d0d0e0;
margin: 10px auto;
width: 937px;
padding: 0;
border: none;
border-width : 0px;
}

#header_img1 {
background-image: url('../images/h_img.gif');
background-repeat: no-repeat;
float : right;
border: none;
border-width : 0px;
margin-top: 0;
width : 252px;
height : 91px;
}

#header_img2 {
background-image : url('../images/h_banner.gif');
background-repeat: no-repeat;
margin-right: 0;
margin-top: 0;
float:right;
border: none;
border-width : 0px;
width : 268px;
height : 91px;
}
