Storage of user data : <p>When looking at how websites such as Facebook stores profile images, the URLs seem to use randomly generated value. For example, Google's Facebook page's profile picture page has the following URL:</p>

<pre><code>https://scontent-lhr3-1.xx.fbcdn.net/hprofile-xft1/v/t1.0-1/p160x160/11990418_442606765926870_215300303224956260_n.png?oh=28cb5dd4717b7174eed44ca5279a2e37&amp;oe=579938A8
</code></pre>

<p>However why not just organise it like so:</p>

<pre><code>https://scontent-lhr3-1.xx.fbcdn.net/{{ profile_id }}/50x50.png
</code></pre>

<p>Clearly this would be much easier in terms of storage and simplicity. Am I missing something? Thanks.</p>
