watch() & setInterval()

[cynthian]

Hi all,
I have this running code below. I'd like to have a function to add into this code that after setInterval is clear, I will display a text below the image.
As I know we can use watch() or listener() in this case, but I don't know how to do it.
If you have any idea, please let me know.
thanks

Cynthia
this is my code
********************

_root.img = 0;
j=0;
picName = "cartoons0178_flash.jpg";

function loadjpg (picName) {
if (j<6){
this.createEmptyMovieClip("holder"+j, 1);
this["holder"+j]._x=0;
this["holder"+j]._y=j*45;
this["holder"+j].loadMovie(picName);
}
j++;
}

function addImg()
{
if (_root.img < 6){
loadjpg(picName);
_root.img++;
}
else{
clearInterval(idImg);
}
}
idImg = setInterval(addImg, 1000);
