   public function infra_product() { 
       if($this->session->userdata('user_name') == TRUE) { 
       $data['user_name']=$this->session->userdata('user_name');

はCodeIgniterのからimage_libライブラリを使用するようにしてくださいを。下記の例をご覧ください。

if ($this->input->server('REQUEST_METHOD') === 'POST'): 
    $this->load->library('image_lib'); 
    $path_parts = pathinfo($_FILES["userfile"]["name"]); 
    $extension = $path_parts['extension']; 
    move_uploaded_file($_FILES['userfile']['tmp_name'], "./uploads/img" . "." . $extension); 
    $config['image_library'] = 'gd2'; 
    $config['maintain_ratio'] = TRUE; 
    $config['create_thumb'] = TRUE; 
    $config['overwrite'] = TRUE; 
    $config['width'] = 200; 
    $config['height'] = 200; 
    $config['quality'] = 100; 
    $config['source_image'] = "./uploads/img" . "." . $extension; 
    $this->image_lib->clear(); 
    $this->image_lib->initialize($config); 
    $this->image_lib->resize(); 
    endif;
