title: Can upload photo when using the Google Photos API
body: <p>I am trying to upload a photo (jpg image) using the new Google Photos API.
  I am able to get an uploadToken but when I try to create the media item I get the following error:</p>
  
  <pre><code>{
    "newMediaItemResults": [
      {
        "uploadToken": "CAIS+QIAkor2Yr4JcvYMMx..... ",
        "status": {
          "code": 3,
          "message": "NOT_IMAGE: There was an error while trying to create this media item."
        }
      }
    ]
  }
  </code></pre>
  
  <p>Here is a snippet of my code:</p>
  
  <pre><code>import sys
  import json
  import requests
  
  pic = 'image.jpg'
  
  fname = 'read_write_token_creds.json'
  with open(fname) as f:
          data = json.load(f)
  tok = data['access_token']
  
  # Step 1 get an upload token
  
  URL = 'https://photoslibrary.googleapis.com/v1/uploads'
  
  headers = {
  'Content-type': 'application/octet-stream',
  'X-Goog-Upload-File-Name': pic,
  'X-Goog-Upload-Protocol': 'raw',
  'Authorization': 'Bearer ' + tok,
  }
  
  files = {'file': open(pic, 'rb')}
  r = requests.post(URL, headers=headers, files=files)
  upload_token = r.text
  
  # Step 2
  
  album_id = 'AG.....7u'
  URL = 'https://photoslibrary.googleapis.com/v1/mediaItems:batchCreate'
  
  header = {
  'Content-type': 'application/json',
  'Authorization': 'Bearer ' + tok
  }
  
  
  payload = {
    'albumId': album_id,
    'newMediaItems': [
      {
        'description': 'Desc.',
        'simpleMediaItem': { 'uploadToken': upload_token }
      }
    ]
  }
  
  r = requests.post(URL, headers=header, data=json.dumps(payload))
  </code></pre>
  
  <p>When I look at r.text from the requests module, I receive the error message which was given at the top of he message.</p>
