Comporre immagine

[MRj92]

Ho provato così:

var current = 0;
var interval = null;

window.onload = function()
{
        LoadPage();
}

function LoadPage()
{
	//LoadTopBar();
	interval = setInterval('ShowBanner()',700);
}

ffunction ShowBanner()
{
	var iter;
	if(current == 162) location.href = "home.aspx";
	if(current == 150) iter = current + 12;
	else iter = current + 10;
	var banner = document.getElementById("banner");
	banner.style.clip = "rect(15px 0px 0px " + iter + "px)";
	
}

il css è:

#banner{
	clip: rect(15px 0px 0px 0px);
	border: none;
	position: absolute;
}

ma l'immagine non compare! :master:
