<TITLE>Resizeable Popup Window</TITLE>
<script type="text/javascript">

PositionX = 200;
PositionY = 100;

defaultWidth = 500;
defaultHeight = 400;

// Set autoclose true to have the window close automatically
// Set autoclose false to allow multiple popup windows

var AutoClose = false;


if (parseInt(navigator.appVersion.charAt(0))>=4)
{
var isNN=(navigator.appName=="Netscape")?1:0;
var isIE=(navigator.appName.indexOf("Microsoft")!=-1)?1:0;}
var optNN='scrollbars=no,width='+defaultWidth+',height='+defaultHeight+',left='+PositionX+',top='+PositionY;
var optIE='scrollbars=no,width=150,height=100,left='+PositionX+',top='+PositionY;
function popImage(imageURL,imageTitle)
{
if (isNN)
{
imgWin=window.open('about:blank','',optNN);
}
if (isIE)
{
imgWin=window.open('about:blank','',optIE);
}
with (imgWin.document)
{
writeln('<html><head><title>'+imageTitle+'</title><style>body{margin:0px;}</style>');
writeln('<sc'+'ript>');
writeln('var isNN,isIE;');
writeln('if (parseInt(navigator.appVersion.charAt(0))>=4){');
writeln('isNN=(navigator.appName=="Netscape")?1:0;');
writeln('isIE=(navigator.appName.indexOf("Microsoft")!=-1)?1:0;}');
writeln('function reSizeToImage(){');
writeln('if (isIE){');
writeln('window.resizeTo(300,300);');
writeln('width=300-(document.body.clientWidth-document.images[0].width);');
writeln('height=300-(document.body.clientHeight-document.images[0].height);');
writeln('window.resizeTo(width,height);}');
writeln('if (isNN){');
writeln('window.innerWidth=document.images["Madan"].width;');
writeln('window.innerHeight=document.images["Madan"].height;}}');
writeln('function doTitle(){document.title="'+imageTitle+'";}');
writeln('</sc'+'ript>');
if (!AutoClose) writeln('</head><body bgcolor="#FFFFFF" scroll="no" onload="reSizeToImage();doTitle();self.focus()">')
else writeln('</head><body bgcolor="#FFFFFF" scroll="no" onload="reSizeToImage();doTitle();self.focus()" onblur="self.close()">');
