I can't see the pic. But I'd guess it's the same picture that's been circulating the net for quite a while(there's about 3 I think..) that have various stories about the size/type/location of said snake.

... plus many other hoax stories. These are generally called "undetermined" because they can't run them down to a original posting person, but all tell you that the snake is not that big, and is usually not even the correct species for the area. It's just like holding a medium bass towards the camera when you get the picture taken, so it looks like you caught a giant fish.
No biggie.
