Create two files:

PHP file get_image.php:

<?php
//you'll play with dirs / paths later
$file = 'some_image.png';
$type = 'image/png';
header('Content-Type:'.$type);
header('Content-Length: ' . filesize($file));

/**
 * Disclaimer - I am aware using __call to set things isn't anything new, once upon a time, I created an ORM class doing that, but this
 * time I'd like to ask about using this approach actually everytime we need accessors like set/get.
 * 
 * OK, so using accessors is a good practice. But quite boring, isn't it? Even with all this IDEs' support (menu code -> create accessors for me please).
 * 
 * Why not use the __call magic method catching "get/set" methods?
