I recently created a visual quiz app which asks a question and then gives 4 image answers.
The problem that I’m having is that the images don’t shrink the image into their quadrants, but rather, zooms in on the top left corner of the image.
Can anyone tell me what I have to change in the following code to make the images display at a set width (so that they fit in the quadrants proportionally).
Here is what the SWF looks like now. As you can see the images become distorted because they are being stretched. What should happen is that the images be displayed at a fixed width and variable height.

var imgLoader:MovieClipLoader = new MovieClipLoader();
var mclListener:Object = new Object();
this.createEmptyMovieClip("sounds", this.getNextHighestDepth());
mcanswer._visible = false;
RandomArray();
//----------

if (success) {
var tmp = dataXML.firstChild.childNodes;
//_global.audiopath = dataXML.firstChild.attributes.audiopath;

mcanswer.Correct.Title.text = dataXML.firstChild.attributes.text_correct;
mcanswer.Incorrect.Title.text = dataXML.firstChild.attributes.text_incorrect;
if (dataXML.firstChild.attributes.randomize == "true") {
isRandom = true;
}
var t = 0;
for (i=0; i<tmp.length; i++) {
var obj:Object = new Object();
if (isRandom) {
if ((tmp*.attributes.type == "question") || (tmp*.attributes.type == "direction")) {
obj.type = tmp*.attributes.type;
