Hi I’ve try to ask this question to all my friends that do flash but they all say it’s easy but nobody gave me an answer and i starting to think it’s not that easy at all.  
I am trying to get the preview button disappear when the first pic is loaded and the next button disappear when the last pics is loaded in the kirupa xml flash gallery.  
I can’t do it at all , i am just a beginner and i was wondering if any of you guys have an idea what to do, maybe this script can’t be chance in order to do that.  
Thanks alot  
this is the code:  
var tcount =0  
function loadXML(loaded) {  
if (loaded) {  
xmlNode = this.firstChild;  
image = [];  
description = [];  
thumbnails = [];  
total = xmlNode.childNodes.length;  
for (i=0; i\<total; i++) {  
image\* = xmlNode.childNodes\*.childNodes[0].firstChild.nodeValue;  
description\* = xmlNode.childNodes\*.childNodes[1].firstChild.nodeValue;  
thumbnails\* = xmlNode.childNodes\*.childNodes[2].firstChild.nodeValue;

```
    }
    firstImage();
     thumbnails_fn(tcount);
} else {
    content = "file not loaded!";
}

```

}  
preloader.preload\_bar.\_xscale=0  
xmlData = new XML();  
xmlData.ignoreWhite = true;
