[Javascript] Adding attachments with mailto:

[ws at chello.se]

I'd like to make a script that automatically attaches a file to an e-mail 
message
when you click on it. Are the only parameters I can use with mailto: 
subject and body?
Any hint on how I can solve this problem?

Cheers,
L. Johansson

onMouseOver="self.status='Contact us'; return 
true"onMouseOut="self.status=' '; return true">Contact us</A>
