title: How to write Parse Cloud Code to make Thumbnails
body: <p>Assume I have a Table</p>
  
  <pre><code>---------Image-------------
  
  imageFile (File)   |    thumbnail (File)  | Post (a pointer to Post)
  </code></pre>
  
  <p>Any idea how to write a cloud code to take a smaller version of that image in another column?</p>
  
  <p>For example, If a user uploaded a (2000x3500 px) image, Parse will save it in imageFile column, and save its thumbnail in the other column</p>
  
  <p>thanks</p>
