How to embed Images in a powershell email using MailMessage

Question

I have an email that works from PS. What I have been trying to do is include images embedded in the email (not attachments). Below is what I have so far:

function Email
        {   
            $smtpServer = {smtp server}
            $smtpFrom = {email from}
            $smtpTo = {email to}
            $messageSubject = "test"

            $message = New-Object System.Net.Mail.MailMessage $smtpfrom, $smtpto
            $message.Subject = $messageSubject
            $message.IsBodyHTML = $true
            $credentials=new-object system.net.networkcredential({smtpUsername},{smtpPassword})

             # $message.Body = Get-Content "D:\Program Files\CymbaTech_FBNC_AM\CTDataLoader\data\TestBody.html"

        # The line below will add any attachments you have such as log files.
        $message.Attachments.Add("{path}\Image1.png")
        $message.Body = '<img src="cid:xyz">'

            $smtp = New-Object Net.Mail.SmtpClient($smtpServer)
            $smtp.credentials=$credentials.getcredential($smtpserver,"25","basic")
            $smtp.Send($message)
        } 

In the above, I have added image tags to the Body.html file. If I open the html directly, it looks as expected with images showing correctly.

When I send the mail however, the images are just displayed as white boxes with a border. Seems that the script is not loading the images in the file.

Has anyone done similar before and have any suggestions?

You must add images as regular attachments. The HTML body must then reference these attachments though the cid attribute: <img src="cid:xyz"> where "xyz" is the value of the Content-ID MIME attribute on the attachment MIME part.
