WaterMark Image with javascript

Hi all,
I have web application developed by asp.net 2.0 (VS 2005), I have a page displaying a table with thefollowing information: Car Model ,Description and Image.
In the Database i stored image as a path. and i use a datalist control to display these information as a table.

Challenge:
When a car is sold, then i want to display a stamp such as [SOLD] to be displayed over the image.
i tried many ways, such as javascript [attahed code snippet]. but the problem is:
When i minimize the browser the [SOLD]  displayed in the same position that because position:absolute.

<ItemTemplate>
        <br />
        <table border="1" style="width: 100px; height: 100px">
         <tr>
         <td style="width: 100px">
        <asp:Image ID="Image1" runat="server" Height="94px" ImageUrl='<%# Eval("img") %>'
        Width="134px" />
       <script type="text/javascript" language="javascript">
       var top;
       var left;
      top=document.getElementById("DataList1_ctl00_Image1").style.top;
      left=450;
     document.write("<font color='red'><div id='d1' style='left:"+left+"px; width: 100px; position: absolute; top:"+top+"px; height: 100px;font-size:50px;font-color:red'>[SOLD]</div></font>")
          </script> 
     </td>
    </tr>
</table>
<br />
</ItemTemplate>

You should use CSS for this - i did it for a property site.

<div class="imageHolder"><img src="car.jpg"/><img src="sold.jpg" class="sold"/></div>

.imageHolder {
display:block;
width:200px;
height:100px;
position:relative;
}
.imageHolder .sold {
position:absolute;
bottom:0;
left:0;
}

This will then holder a sold sign at the base of the image so you can still see the item on sale/sold but there's a sold image over it.

in action or a variation of it can be seen here

Dear bluefezteam:

thank you very much for your solution, but can I make the image sold in middle of car.jpg image?

bluefezteamCommented:
yes - instead of bottom:0; you just need to know the height of your JPEG and divide that by 2, then remove the height of the sold.jpg divided by 2.

Eg

the car graphic is 100px high - its mid point is 50px.
The sold image that sits on the top is 30px - its mid point is 15px.

this means to get sold.jpg to appear over the middle of the the car.jpg you pocition it from TOP or BOTTOM by 50-15 = 35px.
