Thumbnail?

What up everyone
I had made a gallery with 10 thumbnails. When the TN is clicked I would like the image to open in a new window. I C/P this script from the pop up window tutorial

on (release) {
//customize the window that gets opened
// 0 equals NO.
// 1 equals YES.
address = “http://www.paint.html”;
target_winName = “paint”;
width = 600;
height = 300;
toolbar = 0;
location = 0;
directories = 0;
status = 0;
menubar = 0;
scrollbars = 1;
resizable = 0;
//sends data back to the function
openWinCentre(address, target_winName, width, height, toolbar, location, directories, status, menubar, scrollbars, resizable);
}

Then I placed this script in a layer above

_global.openWinCentre = function(url, winName, w, h, toolbar, location, directories, status, menubar, scrollbars, resizable) {
getURL(“javascript:window.open(’”+url+"’,’"+winName+"’,’"+“width=”+w+",height="+h+",toolbar="+toolbar+",location="+location+",directories="+directories+",status="+status+",menubar="+menubar+",scrollbars="+scrollbars+",resizable="+resizable+",top=’+((screen.height/2)-("+h/2+"))+’,left=’+((screen.width/2)-("+w/2+"))+’"+"’);void(0);");
};

The problem is it only works for one TN
Can any help me with this one
