Vale, pero del script:
Código PHP:
<script>
window.onload=function() {var elDiv = document.getElementById('imgContainer');var losFondos = new Array('http://www.google.es/images?q=tbn:DZYW1mMFrUXUAM::blog.plozano.net/wp-content/uploads/2008/05/fondos_mayo.jpg','http://www.google.es/images?q=tbn:y3s1SEvsLf2ZIM::i184.photobucket.com/albums/x79/pixvirtual/fc/109/fondos_3d_eFoY8.jpg','http://www.google.es/images?q=tbn:sRIqhc_esi_nZM::photofiltrecastellano.iespana.es/fondos.jpg','http://www.google.es/images?q=tbn:qMh1ZgWUuDVhDM::www.fondosmyspace.com/completos/fondos/1700.jpg');var indice = Math.floor(Math.random()*losFondos.length);elDiv.style.backgroundImage = 'url(' + losFondos [indice] +')';}
</script>
<DIV id=box-lateral>
<DIV id=top></DIV>
<DIV id=imgContainer
style="BACKGROUND-IMAGE: url(http://images.habbos.es/websystem/release_6/box-register/156.gif); BORDER-BOTTOM: #a0a0a0 1px solid; BORDER-LEFT: #a0a0a0 1px solid; PADDING-BOTTOM: 0px; PADDING-LEFT: 5px; WIDTH: 208px; PADDING-RIGHT: 0px; BACKGROUND-POSITION: right bottom; HEIGHT: 175px; BORDER-TOP: #a0a0a0 1px solid; BORDER-RIGHT: #a0a0a0 1px solid; PADDING-TOP: 5px" >
<DIV id=enter><A class=button
href="index.php?s=register"><B><SPAN>Regístrate <IMG
src="http://images.habbos.es/websystem/release_6/flashy_arrow.gif"></SPAN></B><I></I></A>
