            $regex = '/style\s*=\s*(?:".*?\s*\(\s*\'(.*?)\'\s*\).*?")/si';
            $html = $this->document->save();
            preg_match_all($regex, $html, $matches);
            foreach ($matches[1] as $url)
            {
                $html = str_replace($matches[1], $this->rewrite_url($matches[1]), $html);
            }

with this:

$html = $this->document->save();

            // background images
            if ($this->options['apply']['bgr'])
            {
	        $regex = '/style\s*=\s*(?:".*?\s*\(\s*\'(.*?)\'\s*\).*?")/si';
    	        preg_match_all($regex, $html, $matches);

    	        foreach ($matches[1] as $url)
    	        {
    	            $html = str_replace($matches[1], $this->rewrite_url($matches[1]), $html);
    	        }
    	    }
