Python PIL library not working image.thumbnail(size, Image.ANTIALIAS)

I'm trying to debug this script in python from PIL import Image, ImageChops, ImageOps

I've searched all over the problem seems to be "image.thumbnail(size, Image.ANTIALIAS)" here. Anyone have any ideas? Thanks

image = Image.open(f_in)
print "got here"
image.thumbnail(size, Image.ANTIALIAS)
print "cannot get here"
image_size = image.size
if pad:
    thumb = image.crop( (0, 0, size[0], size[1]) )

    offset_x = max( (size[0] - image_size[0]) / 2, 0 )
    offset_y = max( (size[1] - image_size[1]) / 2, 0 )

    thumb = ImageChops.offset(thumb, offset_x, offset_y)

else:
    thumb = ImageOps.fit(image, size, Image.ANTIALIAS, (0.5, 0.5))

thumb.save(f_out)

EDIT Thanks for the quick answer Mark. I figured it out.

I had to:

pip uninstall PIL
sudo apt-get install libjpeg8-dev 
pip install PIL

I didn't have libjpeg installed. Not sure why I didn't get an error.

If the program never gets to the line "cannot get here" then the problem is that thumbnail is throwing an exception. You didn't mention that in the question though, it should have generated an error.

PIL uses lazy image loading - in the open call it might open the file, but it doesn't actually try to read the whole thing in. If your file is corrupt or in the wrong format it will fail once you try to do something with the image, as thumbnail is doing.
