PHP check whether image exists on remote URL

The simplest and fastest way is to use curl if your host supports curl.

     * check remote image file url
    static public function check_remote_file($url)
    	$ch = curl_init();
    	curl_setopt($ch, CURLOPT_URL,$url);
    	// don't download content
    	curl_setopt($ch, CURLOPT_NOBODY, 1);
    	curl_setopt($ch, CURLOPT_FAILONERROR, 1);
    	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    		return true;
    		return false;
