So I’ve finally successfully installed PIL (after many difficulties) on RHEL5 with Django (development version) and Python 2.6 installed at /opt/python2.6.

Running selftest.py shows that everything appears to be installed correctly:

$ python2.6 selftest.py 
57 tests passed.

I can upload .png files and .gif files without difficulties, but run into problems when trying to upload .jpg files using the ImageField: “Upload a valid image. The file you uploaded was either not an image or a corrupted image.”

I saw this other question and ran the test to see if PIL would verify the image, and it did:

>>> from PIL import Image
>>> trial_image=Image.open("/tmp/jordanthecoder.jpg")
>>> trial_image.verify()
>>>

What could be going on? Obviously, allowing JPEG is kind of important. I realize one option is to use a FileField instead and then check to make sure it is one of GIF, PNG, or JPEG, but I’d much rather use the built-in object.

In case this is helpful, here is the verbose display for the shell above:

UPDATE #2:

Okay, so I decided to bypass ImageField altogether and just see what PIL does on its own. This is the code in question (in my views.py file):

def test_image(request):
    i = Image.open("/tmp/jordanthecoder.jpg")
    t = i.verify()
    return HttpResponse("Image is "+repr(i.info))

This is the webpage output:

Image is {'jfif_version': (1, 1), 'jfif': 257, 'jfif_unit': 1, 'jfif_density': (72, 72), 'dpi': (72, 72)}

UPDATE #3

So, these are the modules and paths for the two different systems. I’m not exactly sure why they’re so different and what I can do to change the behavior of the web version.

They actually were using different JSON modules, pretty sure that that makes no difference. Other than that, here are the different modules. Assume these modules are all somewhere in /opt/python2.6/…

Only in the web version:

django.contrib.sessions.*, django.core.email, django.core.handlers.*, django.core.mail, django.core.mimetypes, django.core.os, django.core.random, django.core.smtplib, django.core.socket, django.core.time, django.middleware.*, email.*, encodings.ascii, hmac, mimetypes, mod_wsgi, smtplib, uu

Only in the shell version:

code, codeop, django.core.management.*, readline, rlcompleter, settings, user

Thanks

** UPDATE #4 **

Looks like the problem is that apache is using the incorrect libjpeg.so, whereas python is using the right one. I’ve created a more generalized version of the question that isn’t specific to Django.
