I would greatly appreciate any help.
Here it is the latest evolution of this piece of code :
"""
class TwitpicOAuthRequest(OAuthRequest):
def to_header(self, realm='http://api.twitter.com/'):
headers = super(TwitpicOAuthRequest,
self).to_header(realm=realm)
return {'X-Verify-Credentials-Authorization':
headers['Authorization']}
def post_photo(request):
if request.method == 'POST':
form = PhotoForm(request.POST, request.FILES)
if not request.session.get('twitter_access_token'):
return HttpResponse("Not authenticated")
if form.is_valid():
access_token = request.session['twitter_access_token']
params = {
'oauth_consumer_key': settings.TWITTER_CONSUMER_KEY,
'oauth_signature_method':"HMAC-SHA1",
'oauth_token':access_token.key,

'oauth_version':'1.0'
}
consumer =
oauth.OAuthConsumer(key=settings.TWITTER_CONSUMER_KEY,

settings.TWITTER_VERIFY_CREDENTIALS

copine_moi.jpg","rb"))
]
register_openers()
datagen, heads = multipart_encode(values)
headers.update(heads)

else:
