Hi

Does anyone know if you can use buttons for the panzoom panning instead of dragging on this:

yes u can, here the html i used that worked for me with the buttons.
the only file i used is jquery.panzoom.min.js in the same folder of the html.

<!doctype html>
<html>
  <head>
    <title>Panzoom for jQuery</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <style type="text/css">
      section { text-align: center; margin: 50px 0; }
    </style>
  </head>
  <body>
	<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
	<script src="jquery.panzoom.min.js"></script>
    <section>
      <h1>Panning and zooming with CSS3</h1>
      <div id="panzoom" style="text-align: center">
        <img src="http://blog.millermedeiros.com/wp-content/uploads/2010/04/awesome_tiger.svg" width="900" height="900">
      </div>
    </section>
    <section class="buttons">
      <button class="zoom-in">Zoom In</button>
      <button class="zoom-out">Zoom Out</button>
      <input type="range" class="zoom-range">
      <button class="reset">Reset</button>
    </section>
    <script>
      $("#panzoom").panzoom({
        $zoomIn: $(".zoom-in"),
        $zoomOut: $(".zoom-out"),
        $zoomRange: $(".zoom-range"),
        $reset: $(".reset")
      });
    </script>
  </body>
</html>
