Can't Display Profile Image using asp .net

Hi

Can't Display Profile Image using asp .net

<asp:Image ID="Image1" runat="server" />

 protected void Page_Load(object sender, EventArgs e)
    {
        try
        {
            if (!Page.IsPostBack)
            {
                lb1.Text = "<b><font color=Brown>" + "Hi.." + "</font>" + "<b><font color=red>" + Session["UserName"] + "</font>";
                bind();
            }
        }
        catch (Exception ex)
        {
            Response.Write("<script>alert('" + ex.Message.ToString() + "');</script>");
        }
       
    }

private void bind()
    {
        SqlConnection con = new SqlConnection(strConnString);
        SqlCommand cmd = new SqlCommand("select image from Login where UserName='" + Session["UserName"] + "'", con);
        con.Open();
        SqlDataReader dr = cmd.ExecuteReader();
        while (dr.Read())
        {
            Image1.ImageUrl = dr[0].ToString();
        }
        con.Close();
   }

Any Idea ..
