[safe]

el codigo de la marquesina es:

Código:

<script language="JavaScript1.2">

var sliderwidth=710
var sliderheight=14
var slidespeed=5

var leftrightslide=new Array()
var finalslide=''
leftrightslide[0]='ACA LE PONES LO QUE QUIERAS QUE PASE POR ELLA '

var copyspeed=slidespeed
//copy contents of leftrightslide into one variable
for (i=0;i<leftrightslide.length;i++)
finalslide=finalslide+leftrightslide[i]+"&nbsp;&nbsp;"


if (document.all){
//dynamically write out the marquee tag
document.write('<marquee id="ieslider" scrollAmount=0 style="width:'+sliderwidth+'">'+finalslide+'</marquee>')
//stop marquee when mouse is over it
ieslider.onmouseover=new Function("ieslider.scrollAmount=0")
//re-enable marquee when mouse is out
ieslider.onmouseout=new Function("if (document.readyState=='complete') ieslider.scrollAmount=slidespeed")
}

function regenerate(){
window.location.reload()
}
function regenerate2(){
if (document.layers){
document.ns_slider01.visibility="show"
setTimeout("window.onresize=regenerate",450)
intializeleftrightslide()
}
if (document.all)
ieslider.scrollAmount=slidespeed
}

//NS specific function for initializing slider upon page load
function intializeleftrightslide(){
document.ns_slider01.document.ns_slider02.document.write('<nobr>'+finalslide+'</nobr>')
document. ns_slider01.document.ns_slider02.document.close()
thelength=document.ns_slider01.document.ns_slider02.document.width
scrollslide()
}

//NS specific function for sliding slideshow
function scrollslide(){
if (document.ns_slider01.document.ns_slider02.left>=thelength*(-1)){
document.ns_slider01.document.ns_slider02.left-=slidespeed
setTimeout("scrollslide()",100)
}
else{
document.ns_slider01.document.ns_slider02.left=sliderwidth
scrollslide()
}
}
window.onload=regenerate2

</script>

Aunque te advierto que en firefox no funciona
