V3-thumb mx modif help please

hi,
i took liberty to use the V3_with_thumbs zip - posted in Best of Kirupa
i’ve try to change the code to have the bigger picture to be place in a popup window instead of the flash movie.
I’m having trouble getting done. when click on the thumb it launch a browser window and my computer window where the file is located but does not show the pic inside the browser window.

BTW i took out the function loading the big pic inside the flash movie (clean, not sure)

here a sample of the code i’ve added:

function activateButtons() {
mainButtons();
for (var i = 0; i<pArray.length; i++) {
var but = th_nav[“thmb”+i];
but.id = i;
but.onRelease = function()
//i want it to launch a brower window
[COLOR=Blue]{getURL(“large/”+images[index],"_blank");}
[/COLOR]
};

i also tried:
[COLOR=Blue]{getURL(“large/”,"_blank");}[/COLOR]

can someone help me with that please.

cheers
