Silly me forgot to ask for proper pics of our 12week scan, and all we have are x-ray pics. Can anyone give me some tips on taking photos of them with the camera?

I tried against the window but ended up getting everything else in the background through the clear bits in the film (bugger!). And every other shot I have done gets background bits and blurs the u/s.

I also have a flat bed scanner but like I thought, that didn't work at all!
