resize img two times

[eluser]Unknown[/eluser]
Hello,
so the problem is this: I upload image, call my create thumb function and it creates the first file but not the second? And I don't know why.

My code:

Code:

function _createThumb($fileName){
   $this->load->library('image_lib');

   $this->image_lib->clear();
   $config['image_library'] = 'gd2';
   $config['source_image'] = 'media/uploads/pictures/' . $fileName;
   $config['new_image'] = 'media/uploads/pictures/thumbs/' . $fileName;
   $config['maintain_ratio'] = TRUE;
   $config['width'] = 150;
   $config['height'] = 100;
   $this->image_lib->initialize($config);
        
   if(!$this->image_lib->resize()){
       return $this->image_lib->display_errors();
   }
  
   $this->image_lib->clear();
   $config['new_image'] = 'media/uploads/pictures/thumbs2/' . $fileName;
   $config['width'] = 200;
   $config['height'] = 150;
   $this->image_lib->initialize($config);

   if(!$this->image_lib->resize()){
       return $this->image_lib->display_errors();
   }

   return 1;
}

I get no error
