[F8] MovieClipLoader assistance

[MyFriendIsATaco]

I know how to load clips/images with the MovieClipLoader class, but what I want to load is say 10 thumbnails and have one progressbar for all of the items, so itll say its done loading when all 10 thumbnails are loaded. Is there an easy way to do it? I've done it before by setting a variable for how many there are total, and after each onLoadComplete call, I add one to the variable until it reaches how many its supposed to do. basically i want to do this:

loader.load("image1.png");
loader.load("image2.png");
loader.load("image3.png");
loader.onAllFinished = function():Void
{
    trace("all the images are loaded");
};

thanks in advance!
