Add these lines for uploading images and files while sending email.

$config2 = array(
         'upload_path'=>'../admin/images/blogimages',
        'allowed_types' => 'pdf|doc|docx',
        'max_size' => 20000,            
        );
        $this->load->library('upload', $config2);
        $this->upload->do_upload('attachment'); 
        $upload_data = $this->upload->data();

        $this->email->attach($upload_data['full_path']);
