Passing an object as a paramter between windows

Many weeks ago :-)
i was asking about passing parameters to a  new window.
And thanks to help from you people, i got it going successfully.

So now,  a full-size image is opened up in my "imageWindow"  (which i call
'HHPhotoSingle.htm')  when you click on a thumbnail
http://mysite.freeserve.com/bbm/hagar/HH/HHVolBTCV.htm
----------------------------------------------------------------------------
-------------------------------------------------
JS Code:
http://mysite.freeserve.com/bbm/hagar/HH/HH_Photos.js

function openWindow(contentURL,windowName,windowWidth,windowHeight) {
 widthHeight = 'height=' + windowHeight + ',width=' + windowWidth;
 newWindow = window.open(contentURL,windowName,widthHeight);
 newWindow.focus()
}

//I've no idea what "windowName" is for, i think i can drop it as an
argument as it never changes, but this is not an issue for now

----------------------------------------------------------------------------
-------------------------------------------------
http://mysite.freeserve.com/bbm/hagar/HH/HHVolBTCV.htm
Code in my HTML page defines the file name and path, the title, and the
window dimensions:

<a href="javascript:openWindow(HHPhotoSingle.htm?Pic=VolBTCV/BTCV01,Pete our
esteemed leader','myNewWindow',800,600)">
      <img alt=".........."/>
    </a>
----------------------------------------------------------------------------
-------------------------------------------------

Code in my HHPhotoSingle.htm :
http://mysite.freeserve.com/bbm/hagar/HH/HHPhotoSingle.htm

var mytext =location.search.substring(1);
var i = mytext.indexOf("=");
var j = mytext.indexOf(",");

   photoname = mytext.substring(i+1, j);
   phototitle = mytext.substring(j+1);

   document.write("<h1>" + unescape(phototitle) + "</h1>");
   document.write("<img src='images/" + photoname + ".jpg' />");

----------------------------------------------------------------------------
-------------------------------------------------
----------------------------------------------------------------------------
-------------------------------------------------

However:
I have now advanced ;-)
to using associative arrays;

My (offline) js now has an array called AllPhotos, such that i have  'photo'
objects, all about one photograph, things like:

AllPhotos.BTCV08.file
AllPhotos.BTCV08.path
AllPhotos.BTCV08.title
AllPhotos.BTCV08.alt
AllPhotos.BTCV08.width
AllPhotos.BTCV08.height

I know i need to use
AllPhotos.BTCV08.width
AllPhotos.BTCV08.height
in the call to openWindow;

but is there any way, using Client-side scripting (I'm not yet advanced
enough for server-side!) that i can pass the BTCV08 *photo object* to the
HHPhotoSingle.htm , via the openWindow call?

I can only see how to pass text strings, as i am currently doing;
but as a VB6 programmer, i like to think that i *can* pass an object (by
reference) to this new window.

However - my JS books and my JS knowledge are not up to it!

Any explanation and help much appreciated :-)
