title: Click an image to bring up a bigger image in a small popup window
body: <p>I am trying to create a function where the user can click an image and a bigger one will load in a small popup window. I already have the bigger image in the system so it merely needs to load the image but in a window the right size!</p>
  
  <p>Any ideas how I can achieve this?</p>
  
  <p>Thanks.</p>
