Yep, Peng, that's right - as I said before, someone who really wants it will always find a way to steal images - this is just a way to make it not so easy. Editing the .htaccess is pretty cool ... hehe, did that myself and it works pretty well but that won't stop stealing images by right click and save either. If people just would respect other people's copyright.
