Images in the browser without refreshing

I want to see images in my browser every 5 seconds, for example, and I think AJAX is a pretty good idea to avoid refreshing page.

I'm using VS2005 (programming in C#) and I've executed an example that works fine: push a button and upload a new image to the browser without refreshing.

The script code is as follows:

<script>
function SumaValores_CallBack(response){
if (response.error != null){
alert("Los valores introducidos no son válidos.");
return;
}
target="contenido";

document.getElementById(target).innerHTML = response.value;

}

</script>
</head>
<body>
<form>
<div>
</div>

<input>
<div></div>

</form>
</body>
</html>

The code in the server is the following:

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
AJAX.Utility.RegisterTypeForAJAX(typeof(_Default));
}

[AJAX.AJAXMethod()]
public string SumaValores()
{

return ("

");

}
}

But I'd like to "refresh" the image every 5 seconds. I've tried to write in the HTML the following tag:

<body>

It didn’t work. How can I make it work?
