What is the purpose of the PHP script provided in the forum thread and how does it function to display images from a folder?

The purpose of the PHP script provided in the forum thread is to display images from a specific folder on a web page. The script uses the `scandir()` function to scan the specified folder for image files, then loops through the files and displays them on the webpage using an `<img>` tag. 

&lt;?php
$folder = &#039;images/&#039;;
$files = scandir($folder);

foreach ($files as $file) {
    if (in_array(pathinfo($file, PATHINFO_EXTENSION), [&#039;jpg&#039;, &#039;jpeg&#039;, &#039;png&#039;, &#039;gif&#039;])) {
        echo &#039;&lt;img src=&quot;&#039; . $folder . $file . &#039;&quot; alt=&quot;&#039; . $file . &#039;&quot;&gt;&#039;;
    }
}
?&gt;
