The original images which was published http://realscifi.fotopages.com/?entry=1235415&back=http://realscifi.fotopages.com/?page=0#CommentsTop(here) earlier was a fake image propoganda by anonymous email creator with no clear objective. These emails on fake pictures of Sungai Jagong was widely spread throughout emails and the Internet.
The real story behind is that there was no sign of waterfall in Sungai Jagong (not even a river). The nearest river (with no waterfall) is Sungai Merbuk. Sungai Jagung is just a mere paddy field.
