You need to user JavaScript for this. You could try the following:
Suppose you have two pages:
Page1.aspx
Page2.aspx

The Image control and the hyperlink are in Page1.aspx.
In Page1.aspx, add the following Javascript code (inside the script tag):

function RefreshImage()
    {
        document.getElementById["FunnyImage"].attributes.item["src"]="<whateverimage.jpg";
    }

Where FunnyImage is the “ID” of the image control.

Im Page2.aspx, add the following Javascript code (inside the script tag, of course):

private void CloseWindow()
{
    StringBuilder sb = new StringBuilder();
    sb.Append("window.opener.RefreshImage();");
    sb.Append("window.close();");

    ClientScript.RegisterClientScriptBlock(this.GetType(), "CloseWindowScript", 
        sb.ToString(), true);
} 

And call the CloseWindow() function from wherever you need.

Hope this helps.
