ActionScript 2.0 :: Dynamic Image Gallery - Loop Through Array

I need to create a dynamic image gallery. The files are defined in an array like imgs = ['img1.jpg','img2.jpg']; then I loop through the array. The images should be arranged horizontally..

Code:
this.imgs = ['test.jpg','bla.jpg'];
var x = 0;
var y = 0;
var i;
for (i in imgs) {
var t = this.createEmptyMovieClip ("thumbnail" + i, i);
var c = t.createEmptyMovieClip ("picHolder", 0);
var thumb = imgs[i];
c.loadMovie (thumb);
c._x = x + i * c._width;
c._y = y;
}
