How can the use of session_start() impact the ability to display images in PHP?

When using session_start() in PHP, it is important to place it at the beginning of the script before any output is sent to the browser. If session_start() is called after output has already been sent, it can cause issues with displaying images or other content on the page. To solve this issue, make sure to call session_start() at the very beginning of your PHP script.

<?php
session_start();

// Your PHP code here
?>
