Hi, i want get images through generic handler classes...

protected void btnSubmit_Click(object sender, EventArgs e)
 {
     SqlConnection connection = null;
     try
     {
         FileUpload img = (FileUpload)imgUpload;
         Byte[] imgByte = null;
         if (img.HasFile && img.PostedFile != null)
         {
             //To create a PostedFile
             HttpPostedFile File = imgUpload.PostedFile;
             //string Filename = Path.GetFileName(imgUpload.PostedFile.FileName);
             //imgUpload.SaveAs(Server.MapPath("~/images/"+Filename));
             //Create byte Array with file len
             imgByte = new Byte[File.ContentLength];
             //force the control to load data in array
             File.InputStream.Read(imgByte, 0, File.ContentLength);
         }
         // Insert the picture tag and image into db
         string conn = ConfigurationManager.ConnectionStrings["ProductConnectionString1"].ConnectionString;
         connection = new SqlConnection(conn);
         connection.Open();
         string sql = "INSERT INTO Album(Picture_Tag,Pic) VALUES(@tag,@pic) SELECT @@IDENTITY";
         SqlCommand cmd = new SqlCommand(sql, connection);
         cmd.Parameters.AddWithValue("@tag", txtTags.Text);
         cmd.Parameters.AddWithValue("@pic", imgByte);
         int id = Convert.ToInt32(cmd.ExecuteScalar());
         lblResult.Text = String.Format("Picture ID is {0}", id);
         ListView1.DataBind();
     }
     catch
     {
         lblResult.Text = "There was an error";
     }
     finally
     {
         connection.Close();
