How can PHPMailer be utilized to easily implement embedded images in emails?

To easily implement embedded images in emails using PHPMailer, you can use the `addEmbeddedImage()` method to attach images and reference them in the HTML content of the email. This allows the images to be displayed inline within the email rather than as attachments.

// Create a new PHPMailer instance
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

$mail = new PHPMailer(true);

// Add embedded image
$file = 'path/to/image.jpg';
$cid = $mail->addEmbeddedImage($file, 'my-unique-id', 'image.jpg');

// Set HTML content with embedded image
$mail->isHTML(true);
$mail->Body = '<img src="cid:' . $cid . '">';

// Send the email
$mail->send();
