title: How to get bigger size picture of Instagram user
body: <p>I'm writing an application to get all the relevant media based to a user or a tag. 
    I was able to the media but the resolution of the user's profile picture found under <code>data/user/profile_picture</code> is quite poor (around 150*150px). </p>
  
  <p>So my question is : is there anyway to get a user profile's picture in a bigger size ? Here are the queries I use to retrieve the media : </p>
