Umm...I don't know if the function is yours, mine, or ours at this point.
It uses it like this:
$mail->AddAttachment("/tmp/image.jpg", "new.jpg");
and I just want to $mail->AddEmbeddedImage("myhost.com/me/smiley.gif", "myhost.com/me/laugh.wav")
but it just throws an error.
There are no directions with this mailer. I've been guessing all night and it's a miracle I've gotten it to half-way work.
