但是当我打开iPhone时，它没有向我显示图像。我在PHP中的发布代码是：
<?php
$email_to = '';
$email_subject = sec("subject");
$email_message = "<html><body>".$_POST['message']."</body></html>";
$fromaddress = "From: xxxxx$gmail.com ,'r'n";
$fromaddress .="BCC: ".$email_address."'r'n";
$fromaddress .= 'Content-Type: text/html';
mail($email_to, $email_subject, $email_message, $fromaddress);
?>
如果我通过gmail连接，我确实会看到你的图片，所以代码有什么问题
我没有尝试你的代码.但似乎很好. 我能看到的唯一问题是 图像路径 .对于邮件模板，图像需要从服务器而不是从文件夹目录加载。
例如：<img src="mailtest/images/bigImg.png" alt='featured image' data-default="placeholder" data-max-width="300" width='326' height='269' > 将是
` <img src="http://www.yourdomain.com/mailtest/images/bigImg.png" alt='featured image' data-default="placeholder" data-max-width="300" width='326' height='269' >
因此，请更改图像路由。希望它的作品。谢谢
出于安全原因，垃圾邮件过滤器可能只阻止邮件中的图像。
我会使用这种方法来解决问题：将图像插入 html 电子邮件中，而无需物理插入它们
图像可以在 HTML 电子邮件中显示，而无需物理插入它们。
这样可以减小电子邮件大小，因为图像不会随电子邮件一起传输。因此，当过滤规则考虑电子邮件的大小时，被困在电子邮件过滤器中的可能性较小。
