How can PHP developers troubleshoot issues with background colors and graphics not displaying correctly in HTML emails sent via pear mime mail?

Issue: If background colors and graphics are not displaying correctly in HTML emails sent via pear mime mail, it may be due to the email client not supporting certain CSS properties or image formats. To troubleshoot this issue, developers can inline CSS styles, use tables for layout, and ensure images are properly hosted and linked in the email. PHP Code Snippet: 

<?php
require_once "Mail.php";
require_once "Mail/mime.php";

$from = "sender@example.com";
$to = "recipient@example.com";
$subject = "HTML Email with Background Colors and Graphics";
$html = "<html>
<head>
<style>
  body {
    background-color: #f0f0f0;
  }
</style>
</head>
<body>
<h1>Hello World!</h1>
<img src='https://example.com/image.jpg' alt='Image'>
</body>
</html>";

$crlf = "\n";
$mime = new Mail_mime($crlf);
$mime->setHTMLBody($html);

$headers = array(
  'From' => $from,
  'To' => $to,
  'Subject' => $subject,
  'Content-Type' => 'text/html; charset=UTF-8'
);

$body = $mime->get();
$hdrs = $mime->headers($headers);

$mail = Mail::factory('mail');
$mail->send($to, $hdrs, $body);
?>
