in design page use this.

<asp:content contentplaceholderid="contentplaceholder4" runat="server">      <img id="img1" runat="server" />  </asp:content>

and in code behind link button click event below:

protected void lkbutton_click(object sender, eventargs e)      {          img1.src = "~/images/sonata-logo.png";      }

i tested it's working fine. put correct path of image show. thanks
