In PHP, what steps should be taken to troubleshoot and resolve the issue of images not displaying correctly in an HTML newsletter?

Issue: Images may not display correctly in an HTML newsletter due to incorrect file paths, missing image files, or server configuration issues. To troubleshoot and resolve this issue, ensure that the image file paths are correct, the image files are accessible, and the server allows image file access. PHP Code Snippet: 

<?php
// Define the base URL for the images
$base_url = "https://example.com/images/";

// Define the image file name
$image_name = "image.jpg";

// Check if the image file exists
if (file_exists($base_url . $image_name)) {
    // Display the image in the HTML newsletter
    echo '<img src="' . $base_url . $image_name . '" alt="Image">';
} else {
    // Display an error message if the image file is not found
    echo 'Image not found';
}
?>
