title: How can I force a tikz image to go to the bottom of the page?
body: <p>I'm using this code to implement a "background image" on my page:</p>
  
  <pre><code>\tikz[remember picture,overlay] \node[inner sep=0pt] at (current page.center){\includegraphics{Images/picture.pdf}};
  </code></pre>
  
  <p>However, I'd like it to show up at the bottom of the page. I've tried changing the <code>current page.center</code> and played around with <code>\vfill</code> but I can't quite figure it out.</p>
