[javico40]

Si tienes razon me equivoque al escribir quise decir que saca por php de la base de datos las rutas a las fotos, aqui esta el codigo magico:

Código:

<script>
<!--
var zoom = 4;
var speed = 4;
var real = 0;
var intervalIn;
var divs = document.getElementsByTagName('div');
for (var i=0; i<divs.length; i++)
{
  if (divs[i].id == 'livethumbnail')
  {
	var myimg = divs[i].getElementsByTagName('img')[0];	
	myimg.smallSrc = myimg.getAttribute('src');
	myimg.smallWidth = parseInt(myimg.getAttribute('width'));
	myimg.smallHeight = parseInt(myimg.getAttribute('height'));
	divs[i].onmouseover = scaleIn;
	divs[i].onmouseout = scaleOut;
	if (!myimg.smallWidth)
    {
