IE versus Netscape

Please help if you can. I'm using an array to load images into image tags on
a HTML page and it works fine with Internet Explorer, but not with Netscape.
I know Netscape users layers instead of all but I tried just changing
document.all to document.layers and it didn't work. Does anyone know how I
would translate this piece of Javascript written for IE into Netscape lingo?

if(document.all[imgname]){
     document.all[imgname].src=imgsrc[p];
     document.all[imgname].alt=orderno[p];
     document.all[imgname].title=adtitlesrc[p];
     document.all[imgname].border=0;
     allocations++;
    }

Thanks in advance
