i have 2fileupload control 2 button and 2 <asp:image>

i want when user select their image from FUP and click on button it show their selected image into image tag so i should bind image tag from database but  i don't know where should i write code that bind my image tag from database 

these are my code

    {
string path = Server.MapPath(".") + "\\../image/House\\";
string filename = System.IO.Path.GetFileName(fup1.PostedFile.FileName);
 fup1.PostedFile.SaveAs(path + filename);

        SqlCommand _cmd = new SqlCommand("Fileup1", _cn);
        _cmd.CommandType = CommandType.StoredProcedure;
        string data = Server.UrlDecode(Request.QueryString["BehCode3"]);

        _cn.Open();
        _cmd.Parameters.AddWithValue("@image", fup1.FileBytes);
        _cmd.Parameters.AddWithValue("@Behcode", data);
        _cmd.Parameters.Add("@id", SqlDbType.Int).Direction = ParameterDirection.Output;

        _cmd.ExecuteNonQuery();
        ViewState["Id"] = _cmd.Parameters["@id"].Value.ToString(); _cn.Close();
        _cn.Close();

    protected void BtnUpload2_Click(object sender, EventArgs e)
    {
 fup2.PostedFile.SaveAs(path + filename);

        SqlCommand _cmd = new SqlCommand("Fileup3", _cn);
        _cmd.CommandType = CommandType.StoredProcedure;
        string data = Server.UrlDecode(Request.QueryString["BehCode3"]);

        _cn.Open();
        _cmd.Parameters.AddWithValue("@image1", fup2.FileBytes);
        _cmd.Parameters.AddWithValue("@Behcode", data);
        _cmd.Parameters.AddWithValue("@id", Convert.ToInt32(ViewState["Id"]));
