title: Dynamically Saving Images to a PDF template
body: <p>I'm building a website where people can pick several pictures from a range.</p>
  
  <p>I then want the users to be able to create a PDF using those pictures.  However I want those pictures inserted in predefined positions and sizes in a template I have already created which will contain other predone materials (words pictures etc).</p>
  
  <p><strong>So my question :</strong></p>
  
  <ol>
  <li>its possible ?</li>
  <li>Can anyone recommend a library which will satisfy my needs, I have had a look and I cant see any PDF libraries that seem to mention templates</li>
  </ol>
  
  <p>Any guidance on where to start will be greatly appreciated.</p>
