Can AS attach image fade to Toggle button?

Question

I have completed my first Flash 8 movie which has an invisible button the size of the image which Stop/starts the movie with AS toggle script below.
click_btn.onRelease=function(){
if(!this.toggle){
chameleon.stop();
} else {
chameleon.play();
this.toggle=!this.toggle;
Can this script be modified so that the movie fades to alpha zero a short time after the stop action, and the re-appears to play instantly when the play action is triggered? If so can anyone help with a script suggestion please.

Thanks again Ned,
A freind of my son worked on this question and following your comments came up with the following code but we cannot make it work.
**Error** Scene=Scene 1, layer=Code, frame=1:Line 1: Syntax error.
     import mx.transitions.Tween;
**Error** Scene=Scene 1, layer=Code, frame=1:Line 2: Syntax error.
     import mx.transitions.easing.*;
Total ActionScript Errors: 2 Reported Errors: 2
Can anyone help fix the code please?
import mx.transitions.Tween;
import mx.transitions.easing.*;
var secNum:Number = 2;
var aTween:Tween;
click_btn.onRelease = function() {
if (!this.toggle) {
chameleon.stop();
aTween = new Tween(chameleon, "_alpha", Quad.easeInOut, 100, 0, secNum, true);
aTween.onMotionFinished = function() {
delete aTween;
chameleon._visible = false;
} else {
aTween.stop();
chameleon._visible = true;
chameleon._alpha = 100;
chameleon.play()
this.toggle = !this.toggle;
