             $u = $this->session->userdata('username');
             $this->db->where('username', $u);
            $result = $this->db->get('user');
            $image_data = $result->row();
            $image = imagecreatefromstring($image_data->Profile_picture);
            header('Content-Type: image/png');
            imagepng($image);
