string lujing = photo + FileUpload1.FileName; //定义lujing ，及图片路径

string connStr = ConfigurationManager.ConnectionStrings["myBlogSQL1ConnectionString"].ConnectionString;
           string insertStr = "insert into photos (图像地址) values (''‘+ lujing + "')";//填入表photos中，取出路径在前台的image控件中显示，也就是把前台的image控件绑定在“图像地址”这个字段上

                int flag = insertComm.ExecuteNonQuery();
                //测试是否添加
                if (flag > 0)
                {   
                    
                Session["flag"] = flag;
                   
                Response.Write("<script language=javascript>alert('添加成功!')");
                Response.Write("windows.documents.location.href='photo.aspx'</script>");
