Programming first image in xml/flash picture gallery?

[Rivana]

I can't figure out how and where to put the code for the size of the instance when loading in photos. I've got it figured for all the other photos since that's programmed via the next and previous buttons etc. But the 'first image' is what appears directly after loading in the xml (except for the loadbar) and I can't seem to get it to conform to the size I want. Where and how to I put it? Why don't I know it? Cuz the code is more or less a direct copy from a tutorial and yeah I get most of it, but this little thing just... *mutters something incomprehensible*

Here's the whole code for the gallery so you can see the logic behind it.
Where does that measly little 'size' thing-y fit in?
Please help...

function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
description = [];
thumbnails = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue;
description[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue;
thumbnails[i] = xmlNode.childNodes[i].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");
