Hi every body I am new here. I am trying to make picture slide show have a built in start delay here is the action script i am using. Is the a way to do flash in flash

speed = 80
imgcount = 23



function moveimg()
{
    for (i = 1; i <= imgcount; i++)
    {
        mc_name = "img" + i;
        _root[mc_name]._x--
        if(_root[mc_name]._x <= (_root[mc_name]._width *-1))
        {
            _root[mc_name]._x += xpos
        }
    }    
}


import flash.display.BitmapData;
xpos = 0;
j=0
for (i = 1; i <= imgcount; i++)
{
    mc_name = "img" + i;
    
    var myBitmapData:BitmapData = BitmapData.loadBitmap(i + ".png");
    this.createEmptyMovieClip(mc_name, this.getNextHighestDepth());
    this[mc_name].attachBitmap(myBitmapData, this.getNextHighestDepth());
    this[mc_name]._x = xpos;
    xpos = xpos + myBitmapData.width;
