image attachments help

["wap" <wap@sinfo.net>]

Hi everyone!
I tried looking in the mail archive about this, but i just cant make it
work....
i need to let the user upload a picture...it is an email form (pretty much
like feddback.html).  The file used to send the email is basically like
/special/feedback.html
example,

[set feedback_active][/set]
[set name=feedback_sent interpolate=1]
[perl arg=sub interpolate=1]
 form_mail
  (
   q{[value email]},
   q{Contact},
   q{[value feedback_email]},
   <<'EOMail' )
  Tema: Contact
  De: [value feedback_name]
  Email: [value feedback_email]
Mensaje
--------
[value feedback_message]
EOMail
[/perl]
[/set]

Now, where should i include the attachment part? i tried using the
report.html as an example, and i know i should use something like (althought
i dont know if this is the correct way):

[if value uploading]
[tag mime type application][/tag]
[tag op=mime type="Uploading"]

any help greatly appreciated....
Thanks
