What steps can be taken to troubleshoot issues with PHP code that is not displaying images correctly or consistently, such as always showing the same avatar in a forum?

The issue of not displaying images correctly or consistently in PHP code can often be due to caching problems. To solve this, you can add a random query string to the image URL to ensure that the browser fetches a fresh copy of the image each time it is loaded. 

<?php
$imageUrl = "path/to/image.jpg";
$imageUrl .= "?t=" . time(); // Add a random query string to force browser to fetch a fresh copy
echo "<img src='$imageUrl' alt='avatar'>";
?>
