function NewWindow(mypage,myname,w,h,scroll,pos){
if(pos=="random"){LeftPosition=(screen.width)?Math.floor(Math.random()*(screen.width-w)):100;TopPosition=(screen.height)?Math.floor(Math.random()*((screen.height-h)-75)):100;}
if(pos=="center"){LeftPosition=(screen.width)?(screen.width-w)/2:100;TopPosition=(screen.height)?(screen.height-h)/2:100;}
else if((pos!="center" && pos!="random") || pos==null){LeftPosition=0;TopPosition=20}
settings='width='+w+',height='+h+',top='+TopPosition+',left='+LeftPosition+',scrollbars='+scroll+',location=no,directories=no,status=no,menubar=no,toolbar=no,resizable=no';
win=window.open(mypage,myname,settings);}
</script>
...
<a href="slika.php?slik=$line[slika]" onclick="NewWindow(this.href,'Picture','400','550','no','center');return false" onfocus="this.blur()">...</a>

Problem je sledeci: sa prvim ucitavanjem popup je aktivan prozor svi ostali su u pozadini, ako se klikne na drugi link(na glavnoj strani), druga slika se ucitava ali popup ostane u pozadini. meni bi trebalo da svaki put kad dode do promene slike popup bude aktivan.
moze li to nekako da se resi?
Sledeci problem je: ako imam slike razlicitog formata prozor nece da promeni velicinu. Npr:

Code:
<a href="slika.php?slik=$line[slika]" onclick="NewWindow(this.href,'Picture','400','550','no','center');return false" onfocus="this.blur()">...</a>
<a href="slika.php?slik=$line[slika]" onclick="NewWindow(this.href,'Picture','550','400','no','center');return false" onfocus="this.blur()">...</a>

on ostaje pri velicini 400*550.
ima li leka za to?

nadam se da sam razumljivo opisao probleme :-)
