 {
 string filename = Path.GetFileName(Image.PostedFile.FileName);
 string filesize = Image.FileBytes.Length.ToString();
 string filepath = "../Posts/"+filename;
 Image.SaveAs(Server.MapPath("../Posts/" + filename));
 string qry1 = "insert into Images(Image_Name,Image_Size,Image_Path)values('" + filename + "','"+filesize+"','"+filepath+"')";
 SqlCommand cmmd = new SqlCommand(qry1, con);
 cmmd.ExecuteNonQuery();
 }
