class RetinaThumbnailResponder extends ThumbnailResponder
{
    
    
    public function parseRequest()
    {
        parent::parseRequest();
        if(strpos($this->file, '@2x') !== false) {
            $this->file = str_replace('@2x', '', $this->file);
            $this->width = $this->width * 2;
            $this->height = $this->height * 2;
        }
    }
    
}



// Then in bootstrap code:

..........
$app->initialize();

$app['thumbnails'] = $app->share(
    function ($app) {
        $responder = new RetinaThumbnailResponder($app, $app['request']);
        return $responder;
    }
);
