You can do it like this
<script type="text/javascript">
 
function ChangeImage(imgbtn)
    {
        imgbtn.src="Images/cart.jpg";
    }
 
 
 
</script>
 
 
 
 <asp:ImageButton ID="ImageButton2" runat="server" 
                    ImageUrl="~/Images/barrels.jpg" onclick="javascript:ChangeImage(this)" />

Sorry it should be OnClientClick and not onclick

<asp:ImageButton ID="ImageButton1" runat="server" OnClientClick="javascript:ChangeImage(this)" />

Thanks that seems to have worked although I have a small problem of when the page postback on the image button click the image changes back to it's orginally one.  Any suggestions on how to work around this?
