Movieclips

Hello. I am trying to create several movieclips dynamicly, why wont my code work? I can only see the last mc that I create…

*imgFolder *is path to image folder and imgArray is an array with all the images in that folder…


//load all images
for(imgIndex;size>imgIndex;imgIndex++){
	loadThumb();
}

//load thumbnail------------------------------------
function loadThumb(){
	// make a movieclip for each of the jpeg's
	createEmptyMovieClip("thumb"+imgIndex,1);
	// load in the jpeg
	loadMovie(imgFolder+imgArray[imgIndex],"thumb"+imgIndex);
	//placement
	setProperty("thumb"+imgIndex,_x,imgIndex*42);
	setProperty("thumb"+imgIndex,_y,0);
}
