How does Instagram name uploaded files?
<p>I have recently been doing some research on Instagram and its API and have come across its strange file naming. Here is an example:</p>

<p><a href="https://scontent-lhr3-1.cdninstagram.com/t51.2885-15/11357983_574786385995155_503550105_n.jpg" rel="nofollow noreferrer">https://scontent-lhr3-1.cdninstagram.com/t51.2885-15/11357983_574786385995155_503550105_n.jpg</a></p>

<p>(The image is supposed to just be black...)</p>

<p>I understand that they used to name files like <a href="https://stackoverflow.com/questions/15778047/how-does-instagram-name-files">this</a> but I cannot seem to find how they are named now. It seems random although I would like to find out if there is any pattern in how Instagram name their files. I would appreciate any information regarding this.</p>
