title: Embed images for use in email message using PHP?
body: <p>I know how to embed an image into an email as an attachment, but that's not really what I want to do. What I want to do is embed an image into the message and use that within the body of the email message itself. Is it possible to do this or possibly reference an attached file somehow to be used in the message?</p>
  
  <p>Should I even worry about this? Is it more beneficial to just load them via a link to the image on my network? I was thinking that this would take some load off my server so it didn't have to be downloaded directly from my site in every email message that got opened, thus reducing bandwidth a little.</p>
  
  <p><strong>Note:</strong> I'm not looking for any email frameworks or libraries etc, just for a simple way to accomplish this task.</p>
