Byte[] img = null;
            Session["image"] = EmpImg;

            if (Session["image"] != null)
            {
                FileUpload FUEMP = (FileUpload)Session["image"];
                if (FUEMP.HasFile && FUEMP.PostedFile != null)
                {
                    HttpPostedFile Myfile = FUEMP.PostedFile;
                    img = new Byte[Myfile.ContentLength];
                    Myfile.InputStream.Read(img, 0, Myfile.ContentLength);
