I am trying to send an html formatted email with inline images from the command line using send-mailmessage. I have looked everywhere and wasn\'t able to find the solution.
You can't do that with Send-MailMessage cmdlet. To include inline image in message you have to write your own function using .NET's Net.Mail.SmtpClient class.
Alternatively, you can just grab David Wyatt's Send-MailMessage function, which already has all you need:
The
Send-MailMessagecmdlet exposes most of the basic functionality for sending email, but you don't get a lot of control over things like attachments or alternate views. Someone on the TechNet forums was asking how to embed images into an HTML mail message, and I decided to write a version ofSend-MailMessagethat supports this. I started with a proxy function for theSend-MailMessagecmdlet, so all of the parameters and usage should be intact. The main difference is that I added an-InlineAttachmentsargument, which accepts a hashtable of pairs in the format'ContentId'='FilePath'. You can then embed the resources into an HTML body by using URLs of the formatcid:ContentId.
