Auto Photo Albums in codeigniter - php

Question

I have used Auto Photo Albums – Multi Level Image Grid for integration of my gallery in my website, it is easily integrated in core PHP but when am using codeigniter frame work for integration of this plugin am unable to get the images
The plugin consists of three files with a directory
reader.php
gallery.html
Reader.php
<?php
//CONFIGURATION
$imgTypes = array('jpeg', 'jpg', 'png', 'gif'); // The extensions of Images that the plugin will read
$imagesOrder = $_GET['imagesOrder']; //byDate, byDateReverse, byName, byNameReverse, random
$folderCoverRandom = $_GET['folderCoverRandom'];
$albumsOrder = $_GET['albumsOrder'];
function getList ($directory, $type='none') {
global $imgTypes;
global $imagesOrder;
global $albumsOrder;
$order = $imagesOrder;
if($type == 'albums'){
$order = $albumsOrder;

Gallery.html
<div class="container-fluid">
