problem using javascript to get querystring

P: n/a
my Problem:
a query string passed into a html page doesn't display correctly on a
I am just using html and javascript (no ASP, PHP or server side

This is the query string:
popup.html?pImage=30_leilani_dowding_b_060.jpg&ord Ref=1000&Title=Leilani Dowding

using the QueryString function below, the pImage variable should be
equal to: 30_leilani_dowding_b_060.jpg
on a PC this is correct BUT on a mac it is displayed as:

Has anyone experienced this problem?

cheers, lion

javascript to to display the image
document.write("<img src=images/wallpapers/"+pImage+" width='128'

javascript function to get query string:
function QueryString(key)
var value = null;
for (var i=0;i<QueryString.keys.length;i++)
if (QueryString.keys[i]==key)
value = QueryString.values[i];
return value;
QueryString.keys = new Array();
QueryString.values = new Array();

function QueryString_Parse()
var query =;
var pairs = query.split("&");

for (var i=0;i<pairs.length;i++)
var pos = pairs[i].indexOf('=');
if (pos >= 0)
var argname = pairs[i].substring(0,pos);
var value = pairs[i].substring(pos+1);
QueryString.keys[QueryString.keys.length] = argname;
QueryString.values[QueryString.values.length] = value;



//set up the variables
//ordRef gets the order Number used i.e: 1000
var ordRef = QueryString("ordRef");
//Title gets the title passed e.g: Jordan&nbsp;Coldanski
var Title = QueryString("Title");
//pImage gets the image name including extension pImage=Jordan128.gif
var pImage = QueryString("pImage");

See the escape() and unescape() function. Use it to correctly encode
your query strings.

For example 'test.html?foo='+escape('big bar')
