title: How to retrieve photo of a telegram contact?
body: <p>In an app, we need to import contacts of a user. We found <a href="https://github.com/enricostara/telegram.link/" rel="nofollow noreferrer">Telegram.Link</a> which implements Telegram API. It has a method that retrieves contacts. A single contact is showed below:</p>
  
  <pre><code>{
  T: api.type.UserContact,
  id: 148049613,
  first_name: "M.",
  last_name: "Barezban",
  username: "Barezban",
  access_hash: "0x47ad17f617b9e945",
  phone: "989363356056",
  photo: {
    T: api.type.UserProfilePhoto,
    photo_id: "0x08d30ecd1b31a7bc",
    photo_small: {
      T: api.type.FileLocation,
      dc_id: 4,
      volume_id: "0x00000000192931a8",
      local_id: 75848,
      secret: "0xac6db13d308318b3"
    },
    photo_big: {
      T: api.type.FileLocation,
      dc_id: 4,
      volume_id: "0x00000000192931a8",
      local_id: 75850,
      secret: "0x4f302deb78247cce"
    }
  },
  status: {
    T: api.type.UserStatusOffline,

  }}
  </code></pre>
  
  <p>I found no way to download the profile photo. which method should I use?</p>
  
  <p>I tried <a href="https://github.com/python-telegram-bot/python-telegram-bot" rel="nofollow noreferrer">python-telegram-bot</a> which implements Telegram Bot API and has two method that could help me: <code>getUserProfilePhotos</code> and <code>getFile</code>.</p>
  
  <p>I tried <code>bot.getUserProfilePhotos(148049613)</code> and got <code>telegram.error.NetworkError: Bad Request: user not found (400)</code>.</p>
  
  <p>I also tried <code>bot.getFile('0x08d30ecd1b31a7bc')</code> and got <code>telegram.error.NetworkError: Bad Request: invalid file id (400)</code></p>
  
  <p>There is also a method named <a href="https://core.telegram.org/method/upload.getFile" rel="nofollow noreferrer">upload.getFile</a> that uses volume_id, local_id and secret but I don't know how to use and call this method.</p>
  
  <p>So how can I download this photo?</p>
