使用 PHP 在电子邮件中嵌入图像

Question

我正在通过本地 smtp 服务器通过 PHP-服务器发送电子邮件。这 HTML- 电子邮件应该包含应该嵌入的图像。我已经设置了 Pear-Extensions Mail，Mail_Mime 和 Net_SMTP。所有电子邮件都发送正常，但没有附加图像。

我已经找到了这个解决方案：PHP Attaching an image to an email，虽然我一步一步地跟着它，但图像仍然没有附加到电子邮件中。我已经尝试通过 $mime->addAttachment("/path/to/image/smile.gif", "image/gif"); 附加图片，但我仍然没有收到任何附件。

    $userGivenName = 'John';
    $userSurname = 'Doe';

    $crlf = "\r\n";
    $mime = new Mail_mime($crlf); 
    $cid = "image001.png";
    $mime->addHTMLImage("/filehost/img/emailLogo.png", "image/png", "", true, $cid);

    $mailtext = '
