Resizing thumbs in thumbnail slideshow

Hey everyone
Well, been getting everything figured out nicely. Mixing scripts from everywhere on this site haha but I can’t seem to figure one thing out. The images I will be using are larger than 300x200, and way larger than the thumbs. How do I have it so that flash will shrink the images down to the right size? I’m going to be busy IRL, and wont have time to make 2 sizes of all the images for my slideshows. So I need flash to do that for me. Can it do that? If so, how do I make the images apear 300x200 and 100x67? Here is my actionscript.


var total;
var p = 0;
var current;
var k = 0;
//variables for slideshow
var slide = 1;
var delay_slide;
//this is the interval between the pics: 6 seconds
var interS = 3000;
function loadXML(loaded) {
    if (loaded) {
        xmlNode = this.firstChild;
        image = [];
        description = [];
        thumbnails = [];
        link = [];
        total = xmlNode.childNodes.length;
        for (var 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);
            link* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
        }
        loadPic(p);
    } else {
        content = "file not loaded!";
    }
}
xmlData = new XML();
xmlData.ignoreWhite = true;

I have tried doing a search, but can’t seem to find how to do it…maybe the code is in front of me and I don’t understand it.
And many thanks to the people here. I have learned much just looking threw the forums.
Thanks for any help:)
