What are some strategies for determining and setting the correct file path for images displayed on a website using PHP?

When displaying images on a website using PHP, it is important to determine and set the correct file path to ensure that the images are displayed correctly. One strategy is to use the `$_SERVER['DOCUMENT_ROOT']` variable to get the root directory of the web server and then concatenate it with the relative path to the image file. This will ensure that the correct file path is used regardless of the server environment. 

<?php
$image_path = $_SERVER['DOCUMENT_ROOT'] . '/images/image.jpg';
echo '<img src="' . $image_path . '" alt="Image">';
?>
