Closing an image opened by Pillow in Window Photo Viewer

[bigmit37]

I'm trying to close each image opened via iteration, within each iteration.

for i in Final_Bioteck[:5]:
     with Image.open('{}_screenshot.png'.format(i)) as test_image:
        test_image.show()
        time.sleep(2)

 My code doesn't seem to close the photos opened via Windows Photo Viewer. 
I also tried,

test_image.close()

 , but no result.




My loop above is opening 5 Windows Photos Viewer dialogs; I was hoping that as I loop through each iteration, each window would be closed.


Thank you.
