Can you please provide the contents of that line from your CodeIgniter installation? What's causing this?

replace if statement with:

if (in_array(substr($filename, -4), array('.jpg', '.png'))
	&& (intval(str_replace(array('.jpg', '.png'), '', $filename)) + $expiration) < $now)
{
	@unlink($img_path.$filename);
}
