Hall!o!^^
Ich bräuchte eine Erläuterung zu zwei Javascripten.
Dh, welcher Bestandteil wofür ''zuständig'' ist und was bewirkt.
Wäre froh, wen jemand helfen könnte
Habe hier das Script zu einem Feenstaub am Mauszeiger:

!-- präsentiert von kostenlose-javascripts.de -->
<script type='text/javascript'>
<!--
var colour="#f0f"; // Farbe des Feenstaubes
var sparkles=50; // Anzahl der "Staubflocken"

Und einmal ein Script, das Bilder ändern lässt:

<script type='text/javascript'>
<!--
var i=0;
function change()
{
if(i==0)
{
document.BEISPIEL.BILD.src="üü.jpg";
i++;
} else {
document.BEISPIEL.BILD.src="lsgoo.jpg";
i--;
}
}

//-->
</script>


Vielen Dank schon im Voraus,
