PIL encoder jpeg not available

I'm working on a picture cropper, and I'm having trouble with my form validation. The form is validated when uploading a GIF picture, but any other format I try raises the following exception:

Upload a valid image. The file you uploaded was either not an image or a corrupted image.

Form

<form enctype="multipart/form-data" method="post" action="/pic/">{% csrf_token %}
    {{ form.as_p }}
    <p><input type="submit" value="View uploaded image"></p>
    <input type="hidden" name="stage" value="crop">
</form>

View

if request.method == 'POST':
        form = ProfilePicForm(request.POST, request.FILES)
        if form.is_valid():
            *do stuff*
        else:
            logger.debug('Form errors == [%s]' % form.errors)

I have installed libjpeg-dev(using apt-get) before installing PIL(using easy_install). At first, I thought this might be due to an incorrect installation of either libjpeg-dev or PIL, but would the problem persists for other formats like png? This problem does in fact occur for png images as well. I'm not getting a jpeg decoder problem, so I'm thinking it's not that, but I'm not sure. Also, I'm using the django development server.

Update

I decided to try a reinstall of PIL. I deleted my PIL install folder /usr/local/lib/python2.7/dist-packages/PIL and my PIL.pth file (in the same dist-packages folder). I ran the setup.py script using sudo python setup.py install. I then ran the selftest.py script, and it fails on the first test:

I'm not sure how to get PIL to work with the unsupported modules listed above. I can verify that I have zlib1g-dev, libfreetype6-dev, liblcms1-dev and libjpeg62-dev, and the libraries themselves installed on my system because when I try to install them with apt-get, it says I already have the latest version.

Answer 1

Try downloading PIL from source, then edit setup.py adding this line:

add_directory(library_dirs, "/usr/lib/i386-linux-gnu")

before this line (214):

add_directory(library_dirs, "/usr/lib")

then

sudo python setup.py install

It should work now
