How to get vendor email from ledgerjournaltrans form

Hi all,

ap->paymentjournal->journal->line

I already created a menuitem to post the journal as email.

but i got stucked to get the vendor email in the "to mail" addresss.

1.I have to get the email of the vendor based on the transaction in ledgerjournaltrans form so that i can send mail to each and every vendor who is in that grid? 

2.how to add images to the email body?

i tried  footerTxt += '<IMG style="HEIGHT: 153px; WIDTH: 445px" src="file:///C:/Users/axadmin/Desktop/sri.png" width=100 height=100>';

please give me any sample code to handle it?

thanks in advance ,

naresh.
