Hvordan gøres dette?

et script i head:

<SCRIPT LANGUAGE="JavaScript"> <!-- gem programmet

browserOk = false;
if ( (parseInt(navigator.appVersion)>=4 )
  || ( navigator.appName == "Netscape"  ) )
  browserOk = true;

function swapImages () {  // preload de forskellige billeder
  this.rude = new Image(15,15)
  this.rude.src = "rude1515.gif"
  this.smil = new Image(15,15)
  this.smil.src = "smil1515.gif"
  this.blink = new Image(15,15)
  this.blink.src = "blink1515.gif"
  this.cool = new Image(15,15)
  this.cool.src = "cool1515.gif"
  return this;
}; //swapImages
A1515 = 0;
if (browserOk) A1515 = new swapImages;

function showGif(navn, id) {
  if (browserOk)
    eval( "document.images." +navn +".src = A1515."+id+".src");
  return true;
}; //showGif
function showRude(navn) {
  if (browserOk)
    eval( "document.images." +navn +".src = A1515.rude.src" );
  return true;
}; //showRude

//--> </script>

de enkelte links bliver så:

<A HREF="predikestolen.html"
    onMouseover="showGif('pstol','blink')"
    onmouseout="showRude('pstol')"><b>Digte, tanker, ...</b></a>
<img src='rude1515.gif' name='pstol' border='0' width='15' height='15'>

<A HREF="windsurfing.html"
    onMouseover="showGif('wsurf','cool')"
    onmouseout="showRude('wsurf')"><b>Windsurfing</b></a>
<img src='rude1515.gif' name='wsurf' border='0' width='15' height='15'>

så mange links du gider, blot de har hvert deres navn.
