Hi!
Sorry, I didn't reply to you pm (have some surgery business going on :(). Just now, they let me out of the hospital until the next operation after tomorrow. The code below is far away from being clean and perfect, but it should do what you want in Mozilla and IE:
//replace everything from below the function scrollerDetect(key) upto
//including the function foo(what) with this code...
var mywin;
var rsyn="no";
var moz=(document.getElementById&&!document.all);
var ie=(document.all);
function popup(url,windowname,width,height) {
widthOrg=width/screen.width;
heightOrg=height/screen.height;
if(widthOrg>1||heightOrg>1){
var factor=heightOrg/widthOrg;
if(factor<=1){
width=screen.width;
height=screen.height*factor;
ins=" width="+(screen.width-8);
rsyn="hor";
}
else if(factor>1){
if(ie){
ins=" height="+(screen.height-20);
}
if(moz){
ins=" height="+(screen.height-35);
}
rsyn="ver";
}
}
else{
ins=" width="+width;
widthOrg=width;
heightOrg=height;
rsyn="no";
width=(width)?width:screen.width/3;
height=(height)?height:screen.height/3;
}
var screenX = (screen.width/2 - width/2);
var screenY = (screen.height/2 - height/2);
var features= "width=" + width + ",height=" + height;
features += ",left=" + screenX;
features += ",top=" + screenY;
features += ",scrollbars=no";
mywin=window.open('about:blank', windowname, features);
mywin.document.write('<html><head></head><body bgcolor=black onunload="window.opener.isClosed=1"><img src="'+url+'" title=" Please click image to close window! " border=0 onclick="window.close()"'+ins+' style="position: absolute;top:0px;left:0px" id="car"></body><html>');
mywin.document.close();
if(rsyn=="hor"){
if(ie){
mywin.resizeTo(screen.width,height);
}
if(moz){
mywin.resizeTo(screen.width,height+25);
}
}
if(rsyn=="ver"){
if(ie){
widthOrg=mywin.document.getElementById('car').offsetWidth+10;
}
if(moz){
widthOrg=mywin.document.getElementById('car').offsetWidth+10;
}
mywin.resizeTo(widthOrg,screen.height);
var newLeft=(screen.width-widthOrg)/2;
mywin.moveTo(newLeft,0);
}
if(rsyn=="no"){
mywin.resizeTo(widthOrg+8,heightOrg+30);
}
mywin.focus();
isClosed=0;
}
var isClosed=0;
var myimage = new Image();
var popupwin=null;
myimage.onload=function(){
popupwin=popup(this.src,"pic",this.width+20,this.height+20)
}
function foo(what){
if (mywin&&isClosed==0){
mywin.close();
}
myimage.src=what;
}
