The aim of the script is to do as much as possible in Javascript (with the HTML5 <canvas> tag), and only the network-related stuffs on the server side. The only little piece of server-side code that remains in the code is just a proxy, used to circumvent the same-origin policy.
We implemented this code both in Javascript (node-app/proxy.js) and PHP (proxy.php), so you just need to have either one
on your server to run dezoomify.
