Suspicious photos
One of the first red flags to go up when considering any extraordinary photograph offered as evidence (of UFOs, Bigfoot, or lake monsters, for example) is an image submitted anonymously. The photographs were taken by an unnamed "member of a disaster team," at an unknown location and date.
Two photos were released; one was taken from a helicopter, the second one wasn't, suggesting that the creature was sighted on two separate occasions. That raises the question as to why there are only two photos; one might expect that a person seeing such an extraordinary creature might snap more than one picture each time.
There's also the interesting composition of the photos: The snake-like creature seems to be posing full-length for the camera. In the aerial photo, it is nicely centered in the middle of the river, and in the other photo it is just high enough above the rooftops in the foreground to see its full length.
Of course it's possible the photographer just got lucky, capturing the giant snake at its most photogenic both times, but that raises another question: If the huge beast spends its time in such high-visibility areas, why is this the first time it's been reported or photographed?
Furthermore, the reported size of the creature cannot be correct. The original estimate given was that the creature was 100 feet long, though the scale of the photos suggest it must be far larger.
Then there's the question of whether the photo was even taken at the Baleh river, since most photographs of its waters show it to be a cloudy river, not the clear, dark blue water seen in the aerial photo. If the photo was actually taken by a disaster team member checking on flooded regions, the flooding runoff would increase the suspended particulates in the water (silt, debris, etc.), creating even cloudier water than usual.
Of course, all these troubling questions vanish if the photographs are simply faked.
They totally look fake to me. The one taken from a helicopter looks really suspicious.
