while retrieving image in byte format from SQL table it is previewing but encripted symbols are also showing @ top of my web page

                    rd.Read();

                    Session["id"] = rd["id"].ToString();
                    ccname.Text = rd["CustomerName"].ToString();
                    ffname.Text = rd["FathersName"].ToString();
                    ddob.Text = rd["Dob"].ToString();
                    ggender.Text = rd["Sex"].ToString();
                    ooccupation.Text = rd["Occupation"].ToString();
                    mmnumber.Text = rd["MobileNumber"].ToString();
                    almnumber.Text = rd["alternativemobilenumber"].ToString();
                    llnumber.Text = rd["LandLineNumber"].ToString();
                    pproof.Text = rd["IdProof"].ToString();
                    iidnum.Text = rd["IdNumber"].ToString();
                    aaddress.Text = rd["Address"].ToString();
                    ccity.Text = rd["City"].ToString();
                    rReference.Text = rd["Reference"].ToString();
                    rrefrelation.Text = rd["ReferenceRelationship"].ToString();

                    Context.Response.BinaryWrite((Byte[])rd[rd.GetOrdinal("Photo")]);


                    rd.Close();

i have tried this method to retrive my image from sql server with the help of store procedure but i could't find an solution is there any changes in my syntax pls give me some suggestion

byte[] bytes = ((byte[])rd["Photo"]);
string imageSource = string.Format("/CustomerImage.ashx?id={0}&id={1}", Session["id"], "{0}");
string strBase64 = Convert.ToBase64String(bytes);
photo.ImageUrl = string.Format(imageSource, strBase64);
con.Close();
