[email] In commons-email, can't display embedded images?

[Amr Hassanin]

Dears,

                I tried to send an email with 4 embedded images , and when I 
received it on Hotmail, it says an attachment exist but neither the images 
displayed nor the attachment.
I used the cid method illustrated on the user guide on your website.

Any ideas how to fix this?

Regards,
Amr
