var doc = req.responseXML;
var cont=document.getElementById("data");
var imgsrc=document.getElementById("pic");
var thumb=document.getElementById("pic_s");
var clickhere=document.getElementById("alink");

//var test = doc.getElementsByTagName('thumb');
var smallpic = doc.getElementsByTagName('thumb');
var lnkxml = doc.getElementsByTagName('link');

imgsrc.src = doc.getElementsByTagName('image').item(0).firstChild.nodeValue;
imgsrc.alt = doc.getElementsByTagName('alt').item(0).firstChild.nodeValue;
thumb.src = smallpic.item(0).firstChild.nodeValue;
clickhere.href = lnkxml.item(0).firstChild.nodeValue;


var rot=document.getElementById("spn1");
rot.innerHTML= smallpic.item(0).firstChild.nodeValue;

thumb.onclick=function()
{

//if(thumb.src==smallpic.item(1).firstChild.nodeValue)
if(rot.innerHTML==smallpic.item(1).firstChild.nodeValue)
{
imgsrc.src = doc.getElementsByTagName('image').item(0).firstChild.nodeValue;
imgsrc.alt = doc.getElementsByTagName('alt').item(0).firstChild.nodeValue;
