Question

I want to upload an image from my hard drive, using an html form:

Image file: <input name="imageupload" id="imageupload" type="file" />

Then I upload it to twitter with:

image=self.request.get('imageupload')
image2=base64.b64encode(image)
twitapi.Update_profile_image(image=image2)

given twitapi.Update_profile_image:

def Update_profile_image(self,image):
    if not self._oauth_consumer:
        raise TwitterError("The twitter.Api instance must be authenticated.")

    url = '%s/account/update_profile_image.json' % (self.base_url)
    data = {'image':image}

    json = self._FetchUrl(url, post_data=data)
    data = self._ParseAndCheckTwitter(json)
    return data

Given _FetchUrl from twitter-api

I always get

TwitterError: There was a problem with your picture. Probably too big.

Any ideas whee it comes from? Thanks!

To submit ah image correctly via a form, you have to include

enctype="multipart/form-data" 

eg

<form  enctype="multipart/form-data" action='/' method="POST">
