Can someone tell me how I can correct the size of my thumbnails and larger images pls. I have attached the fla file and the flash player file in this zip file. I’ve got everything else working but I am not sure what script to use to adjust the image size to the actual file size.

I used the [http://www.kirupa.com/developer/mx2004/thumbnails.htm](http://www.kirupa.com/developer/mx2004/thumbnails.htm) tutorial for vertical scroll but the images are not the right size?

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;  
thumbnails\_fn(i);  
}  
firstImage();  
} else {  
content = “file not loaded!”;  
}  
}  
xmlData = new XML();  
xmlData.ignoreWhite = true;  
xmlData.onLoad = loadXML;  
xmlData.load(“images.xml”);
