Unable to show an image using python PIL Image.show

Question

I'm using the Python Imaging Library and I am unable to open an image successfully in Windows Live Photo Gallery. There is a message that shows up saying "There are no photos or videos selected" instead of the image.

This is what I've tried:

import Image

img = Image.open(r"C:\Users\User\Pictures\image.jpg")
img.show()

This is pretty much the same as in the PIL handbook tutorial, so I'm not sure where I'm going wrong.

The documentation says:

On Windows, it [show()] saves the image to a temporary BMP file, and uses the standard BMP display utility to show it.

Problem is that your program exits immediately somehow, the temporary file is deleted upon exit and Windows etc. cannot find it. As a temporary solution, try adding:

import time
# Your code as above
time.sleep(30)

This will make the program wait 30 seconds before exiting. If you prefer, you could make it wait the user to press a key.

EDIT: it seems like you are experiencing problems with temporary files. As a workaround, save the image somewhere on the disk using, say, img.save("C:\Users\User\Pictures\test.jpg") and open it with your favorite image viewer. Whenever you want to show the processed image, call save again and reload the picture in the image viewer.
