I'm on an iPad and can't find any way to view the flood images. And it would probably have taken only one line of code to enable it to work on all touchscreen devices by adding an on click event.
Revealing the flood image from left to right probably would've worked better, too.
My first reaction was "is this because they drive on the left?"
No, LCD screens work upside-down here, just like our drains are the "wrong" direction.
(Tip for the sarcasm impaired: that's a bad joke.)
