Just tried some code, noticed it does not work clean, want adjust a little, not sure does code required doctype <!DOCTYPE html PUBLIC...? also, what the sense use backslash in html tags?
Code: 
function goImgWin(myImage,myWidth,myHeight,origLeft,origTop,capt) {
var mh = myHeight + 44;
var mw = myWidth + 24;
TheImgWin = window.open('','image','height=' + mh + ',width=' + mw + ',toolbar=no,directories=no,status=no,' + 'menubar=no,scrollbars=no,resizable=no');
TheImgWin.resizeTo(mw+2,mh+30);
TheImgWin.document.write('<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL unfurl="true"]http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html[/URL] xmlns="http:\/\/[URL unfurl="true"]www.w3.org\/1999\/xhtml">');[/URL]
TheImgWin.document.write('<head><title>Popup<\/title><\/head>');
TheImgWin.document.write('<body style="overflow:hidden" bgcolor="#ffffff" onclick="self.close()">');
TheImgWin.document.write('<img src="'+myImage+'" width="'+myWidth+'" height="'+myHeight+'" ');
TheImgWin.document.write('border="0" alt="'+capt+'"\/><p align="center">'+capt+'<\/p>');
TheImgWin.document.write('<\/p><\/body><\/html>');
TheImgWin.moveTo(origLeft,origTop);
TheImgWin.focus();
}

[tt]DOCTYPE[/tt] is mandatory for all HTML documents.

That is the XHTML syntax.

I don't think doctype ans backslash ( \ ) need be used in javascript.

The backslash is used as an escape character so you can do things like this:

Code: 
var strLink = "<a href=\"[URL unfurl="true"]http://tek-tips.com\">Tek[/URL] Tips</a>";

If you want to include a backslash in your js, you need to escape it with one as well

Code: 
var strText = "this is a backslash - \\";

if you are using single quotes, you may need to use it as follows:

Code: 
var strText = 'this is Vic\'s post';



TIP: trying googling the answer before posting, you'll find that more times than not someone else somewhere has had the same request and posted an answer online.

I have recently been semi-converted to ensuring all my code (well most of it) works in both javascript and non-javascript enabled browsers

seems backslash must not be used in js code at all.
