How do u Remove Borders?

Hello people,

I got a link that when its clicked it will open a jpg in a pop up window but its got a white border or margin around it. how do i get rid of this???

The action script i got for my button to load the jpg is:

on (release) {
getURL(“‘Photo 10.jpg’,‘ba1’,‘width=320,height=477,left=0,top=0,toolbar=No,location=No,scrollbars=No,status=No,resizable=No,fullscreen=No’); NewWindow.focus(); void(0);”);
