What are the potential pitfalls or challenges in implementing favicons and image titles in PHP websites?

One potential challenge in implementing favicons and image titles in PHP websites is ensuring that the correct file paths are used for the images. It's important to set the correct path for the favicon and image titles to display correctly across different pages of the website. Additionally, it's crucial to handle errors gracefully in case the image files are missing or inaccessible.

<!-- Set the favicon -->
<link rel="icon" type="image/png" href="<?php echo BASE_URL; ?>/favicon.png">

<!-- Set the image title -->
<title><?php echo $imageTitle; ?></title>
