我想在PowerShell中为电子邮件生成嵌入式图像。但运气不好。我使用<p><img src='file:///C:tempPicture1.png' /></p>
# Email Subject Set Here
$subject="Your password will expire soon"
# Email Body Set Here, Note You can use HTML, including İmages.

谢谢,
不幸的是，直接引用C:上的文件将不起作用(有太多的安全问题)，Send-MailMessage不会拾取它。相反，你有两个选择，而且，听起来令人困惑和琐碎，这在很大程度上取决于你的目标电子邮件程序。
CID图像嵌入
"老派"方法是将图像附加到电子邮件中，并使用内容id (CID)引用将两者链接起来。如果您使用的是桌面Outlook应用程序，这是首选的方法。缺点是人们并不总是信任带有附件的电子邮件，并且发送带有附件的电子邮件会产生垃圾邮件/过滤影响，所以有时不总是首选。此外，一些基于web的电子邮件提供商在正确显示图像方面存在问题。
$body = "<p>.... <img src='cid:Picture1.png' alt='Embedded Image'> ....</p>"
$file = 'C:tempPicture1.png'
Send-Mailmessage -Attachments $File -smtpServer $smtpServer -from $from -to $emailaddress -subject $subject -body $body -bodyasHTML -priority High -Encoding $encoding
内联嵌入将数据嵌入为base64编码数据(基本上将二进制图像数据更改为纯文本)，并由电子邮件客户端/浏览器解码。这意味着没有附件，通常交付更成功。因为base64编码在网络中使用，所有基于网络的电子邮件客户端都不会有显示它们的问题。缺点是桌面版的Outlook 2010+会显示"默认屏蔽的图像"。
$file = Get-Content 'C:tempPicture1.png'
$Bytes = [System.Text.Encoding]::Unicode.GetBytes($file)
$EncodedText =[Convert]::ToBase64String($Bytes)
$body = "<p>.... <img src='data:image/png;base64,$EncodedText' alt='Embedded Image'> ....</p>"
