很长一段时间以来，我一直试图在我的php电子邮件中添加一个png，但没有成功。我尝试了传统的方法，并尝试使用这个网站将Base64添加到html和css中http://www.base64-image.de
但无论我做什么，我都会得到一个空白的标题。有人能一步一步地告诉我，我必须做什么才能在我发送的电子邮件中显示png吗？不，它不能是附件提前感谢
<?php
// $email and $message are the data that is being
// posted to this page from our html contact form
$email = $_REQUEST['email'] ;
$mail2 = new PHPMailer();
// set mailer to use SMTP
$mail2->IsSMTP();
// As this email.php script lives on the same server as our email server
// we are setting the HOST to localhost
$mail2->Host = "smtp.comcast.net"; // specify main and backup server

// When sending email using PHPMailer, you need to send from a valid email address

$mail2->Password = "*******"; // SMTP password
$mail2->SMTPSecure = 'ssl'; // Enable TLS encryption, `ssl` also accepted

这是非常混乱的。为什么您在使用PHPMailer的同时还要呼叫mail()？我不知道你为什么认为你需要像那样手动处理标题——使用PHPMailer这样的库的目的是让你不必担心这样的事情！
如果你只设置Body，PHPMailer不会对你的图像路径做任何事情——你需要将你的身体传递到msgHTML()，它会在那里查找图像并将所有内容转换为嵌入图像。
PHPMailer提供了一些示例，向您展示了如何做到这一点（如果不在examples文件夹中，请查看单元测试）。
我还可以看到，您的代码基于一个旧示例，并且可能正在使用PHPMailer的旧版本，因此我建议您至少更新到5.2.10。
