Hi Vedran,

The question is asking you to read all files from a specified directory. In this case the 'img' directory.

PHP's file() function reads an entire file into an array, as such it isn't meant to be used to read a directory ( a folder ).

The quiz is looking for you to use PHP's scandir() function.

You can read about it here: http://php.net/manual/en/function.scandir.php

 $images = scandir('img');
