How do I use event.target.name in AS2?

Question

Thanks to kglad I was able to see how event.target.name in AS3 could make a button load a movieclip with the same namesake.
I'm doing the same thing now in AS2 but don't know what to write instead of event.target.name.
And so at the moment each button pushes info into an array and then a function uses that to decide which movieclip to attach to a holder after it has faded out once, and then fades in again...
// ***** IMAGE GALLERY START ***** //
// Add image to holder
imgholder.attachMovie("img0", "image0_0", 1)
// Array
var nextLoad = ["img0"];
// Btn listeners
img5.onRelease = function() { trace (nextLoad); nextLoad.pop(); nextLoad.push("img5"); btnClick() } // Written on 1 line
img4.onRelease = function() { trace (nextLoad); nextLoad.pop(); nextLoad.push("img4"); btnClick() }
img3.onRelease = function() { trace (nextLoad); nextLoad.pop(); nextLoad.push("img3"); btnClick() }
img2.onRelease = function() { trace (nextLoad); nextLoad.pop(); nextLoad.push("img2"); btnClick() }
img1.onRelease = function() {
nextLoad.pop();
nextLoad.push("img1");
btnClick()
img0.onRelease = function() {
nextLoad.pop();
nextLoad.push("img0");
btnClick()
// The btn function
function btnClick() {
trace ("click");
var myImgTween:Object = new Tween(imgholder, "_alpha", Strong.easeOut, 100, 0, 1, true);
myImgTween.onMotionFinished = function() {
fadeOutImg();
// The btn function part II
function fadeOutImg() {
trace ("fadeOutImg");
imgholder.attachMovie(nextLoad, "image1_1", 1);
var myImgTween:Object = new Tween(imgholder, "_alpha", Strong.easeOut, 0, 100, 1, true);
I know I should be able to push the button name into the array, but am having to use a string... I'm sure my code is cumbersome!! But it works. I've tried pushing the button name but it end up including the full stage reference.
Is there a cleaner way of doing this using event.target.name?
Thanks for looking!

There is no event.target in AS2. However since AS2 has no way of remembering the scope object where the target object resides, you can use this to your advantage to retrieve the name of the target by using the "this" command in the function whenever you use the above format "mc.onPress = myfunc". FYI, the popular workaround Delegate, made it possible that when you called "this" in the function, you could retrieve the scope object where the target instance resides. So without its use, "this" will return the name of the target object. Anyway this is the code you can use:
imgholder.attachMovie("img0","image0_0",1);
var nextLoad = ["img0"];
img5.onRelease = onImgRelease;
img4.onRelease = onImgRelease;
img3.onRelease = onImgRelease;
img2.onRelease = onImgRelease;
img1.onRelease = onImgRelease;
img0.onRelease = onImgRelease;
function onImgRelease():Void {
   nextLoad.pop();
   nextLoad.push(this._name);
   btnClick();
// The btn function
function btnClick() {
   trace("click");
   var myImgTween:Object = new Tween(imgholder, "_alpha", Strong.easeOut, 100, 0, 1, true);
   myImgTween.onMotionFinished = function() {
      fadeOutImg();
// The btn function part II
function fadeOutImg() {
   trace("fadeOutImg");
   imgholder.attachMovie(nextLoad,"image1_1",1);
   var myImgTween:Object = new Tween(imgholder, "_alpha", Strong.easeOut, 0, 100, 1, true);
