title: Allow users to upload a pic for their profile
body: <p>Oddly enough, I can't find any info on this topic: user profile pictures.</p>
  
  <p>Is there a PHP solution for the following?</p>
  
  <ul>
  <li>Allows users to upload a pic from their hard drive for storage on our server</li>
  <li>Shrinks the image if it's too big; expands it if it's too small (height/width)</li>
  </ul>
  
  <p>Is this easy to build yourself? Or is there already a library for it?</p>
