"tweepy.error.TweepError: Could not determine file type" error when trying to upload jpg image.

[AlbertCoolGuy]

I'm trying to upload a image using this code:

media = api.media_upload('quote.jpg', f)
api.update_status(status="foo", media_ids=[media.media_id_string])

Expected Results

Tweepy uploads the image with the message "foo".

Actual Results

Tweepy fails to upload the image because it can't guess the filetype using imghdr.what().

Possible Solution

Use mimetypes and/or magic as a fallback if imghdr fails.

Traceback

Traceback (most recent call last):
  File "planetexpressbot.py", line 30, in <module>
    media = api.media_upload('quote.jpg', f)
  File "/usr/local/lib/python3.8/site-packages/tweepy/api.py", line 229, in media_upload
    headers, post_data = API._pack_image(filename, max_size,

    raise TweepError('Could not determine file type')
tweepy.error.TweepError: Could not determine file type
