esp32cam capturing and saving image works on repl but not from script

[TecDroiD]

hi,
i want to get some grayscale image from esp32cam module and thought that it's the easiest to capture a raw image, save it and read it via ampy get...

tought...

having the following code in repl:
import camera

camera.init(0,format=camera.GRAYSCALE, framesize=camera.FRAME_VGA)
img = camera.capture()
with open ('image.sc', 'wb') as fp:
   fp.write(img)

I can save my image and read it after

now I have saved same code into a script capture.py, uploaded it and ran..
it hangs at write(img)...
and never wakes up again until i press reset button..

... but why?
