The above would work fine if the value is determined by an event that  
happens only once, but otherwise you'll get multiple t values in the  
query string.  To prevent this possibility, I would wait to set the  
query string in onclick, so it only happens once.  I just used  
window.open out of force of habit since that's what I'm usually doing  
in an onclick event.  But Hassan is right, that really doesn't make  
much sense here.  To work like a normal link (opening in the same  
window), it would be better to do window.location, e.g.:

<a href="img.php?s=<?php echo($value);?>" onclick="window.location =
  this.getAttribute( 'href' ) + '&t=' + t; return false;">Click
here</a>

Peace,
