==================================================
int imgLen = FileUp.PostedFile.ContentLength;
byte[] imgBinaryData = new byte[imgLen];
imgBinaryData = FileUp.FileBytes;
SqlConnection usrcn = new SqlConnection();
usrcn.ConnectionString = ConfigurationManager.ConnectionStrings["connect"].ConnectionString;
SqlCommand cmd_file = new SqlCommand();
cmd_file.Connection = usrcn;
cmd_file.CommandText = string.Format(@"Update ImageTB set Image=@image where imgid={0}", imgid);
cmd_file.CommandType = CommandType.Text;
//欄位型態必為Image
cmd_file.Parameters.Add("@image", SqlDbType.Image).Value = imgBinaryData;
usrcn.Open();
cmd_file.ExecuteNonQuery();
usrcn.Close();

顯示：
ps1：無論哪個設定，請務必設定寬高，使得圖檔大小一致化
