problem using javascript to get querystring

[lion]

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

This is the query string:
popup.html?pIma ge=30_leilani_d owding_b_060.jp g&ordRef=1000&T itle=Leilani&nb sp;Dowding

using the QueryString function below, the pImage variable should be
equal to: 30_leilani_dowd ing_b_060.jpg
on a PC this is correct BUT on a mac it is displayed as:
'30_leilani_dow ding_b_06030_le il'?

Has anyone experienced this problem?

cheers, lion

javascript to to display the image
<SCRIPT LANGUAGE="JavaS cript">
document.write( "<img src=images/wallpapers/"+pImage+" width='128'
height='128'>") ;
</script>

javascript function to get query string:
function QueryString(key )
{
var value = null;
for (var i=0;i<QueryStri ng.keys.length; i++)
{
if (QueryString.ke ys[i]==key)
{
value = QueryString.val ues[i];
break;
}
}
return value;
}
QueryString.key s = new Array();
QueryString.val ues = new Array();

function QueryString_Par se()
{
var query = window.location .search.substri ng(1);
var pairs = query.split("&" );

for (var i=0;i<pairs.len gth;i++)
{
var pos = pairs[i].indexOf('=');
if (pos >= 0)
{
var argname = pairs[i].substring(0,po s);
var value = pairs[i].substring(pos+ 1);
QueryString.key s[QueryString.key s.length] = argname;
QueryString.val ues[QueryString.val ues.length] = value;
}
}

}

QueryString_Par se();

//set up the variables
//ordRef gets the order Number used i.e: 1000
var ordRef = QueryString("or dRef");
//
//Title gets the title passed e.g: Jordan&nbsp;Col danski
var Title = QueryString("Ti tle");
//
//pImage gets the image name including extension pImage=Jordan12 8.gif
var pImage = QueryString("pI mage");
//

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

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