Wenn ich das Hintergrundbild auf volle Groesse maximiere und in der html-datei noch ein paar Bilder im Kreis rotieren lasse, dann tritt der Effekt ein, dass das Hintergrundbild "wackelt". Kann das irgendwer abstellen?
Hier der Quellcode:
########### bgresize.js zum vergroessern des Hintergrundbildes####
NS4=(document.layers);
IE4=(document.all);
ver4=(NS4 IE4);
scaleWidth = false;
scaleHeight = true;
function makeIm() {
winWid = (NS4) ? innerWidth : document.body.clientWidth;
winHgt = (NS4) ? innerHeight : document.body.clientHeight;
imStr = "<DIV ID=elBGim"
+ " STYLE='position:absolute;left:"+pos+";top:0;z-index:-1'>"
+ "<IMG NAME='imBG' BORDER=0 SRC="+imSRC;
if (scaleWidth) imStr += " WIDTH="+winWid;
if (scaleHeight) imStr += " HEIGHT="+winHgt;
imStr += "></DIV>";
document.write(imStr);
}
