<?php
// Rough proxy to help map.js check for photos.
// Reason being that requests similar to http://www.tcd.ie/Maps/photos/small/100.jpg
// were being redirected to http://www.tcd.ie/Maps/photos/small/200.jpg or similar.
// Because the web server is set up to permenantly redirect 301 to files with a similar name.
// JavaScript cannot check for redirects (30x) as they are completed before the JavaScript runs.
// Hence maps.js always got a 200 OK response for redirected photos.
