I think you're looking for the wrong thing. A 30pixel image isn't going to show you much - the pic is the honeycomb image lower on the page.

OK so I know I don't know what I'm talking about...............but................I have seen loads of amazing X_ray images of various astronomical bodies with hi res images and all, so why do they need to have a low res image of lightening? I have taken a few pics of lightening at night, just hold the shutter open for a couple of mins until either you see a flash or the film starts to fog. If you are using an X-ray sensitive chip surely one could hold the shutter open for quite some time before any fogging, after all at any time the background X-ray flux is pretty minimal, so the lightening duration would equate to the exposure time.

Am I being even more stoopid?

They're trying to capture at 10million frames per second to see how the xray radiation moves with the lightning. It's not possible to do very many pixels at this frame rate!
