{
       System.Net.WebRequest webreq = System.Net.WebRequest.Create(HttpUtility.UrlDecode(form["imgphoto"]));
                        System.Net.WebResponse webres = webreq.GetResponse();
                        Stream stream = webres.GetResponseStream();
                        System.Drawing.Image img = System.Drawing.Image.FromStream(stream);
                        MemoryStream ms = new MemoryStream();
                        img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
 
   return ms.ToArray();
