Embedding images without explicit style definitions

Question

I'm designing an app with a big row of buttons.  They are all identical except for the label and icon.  Ideally I would like to be able to define them via ActionScript using a for loop.  I'm stuck on how to embed the icon images though without doing a separate style entry for each button.
example code:
var labels:Array = ["hello", "interior", "exterior", "photos", "videos", "accessories", "games"];
            for each (var s:String in labels) {
                var b:Button = new Button();
                b.label = s;
                buttonBox.addChild(b);
For each button I've got graphics called name.png and name-b.png.  So how would I set the skin and over-skin properties of each button programmatically, as if I had made a separate style for each button ala:
.hello {
   skin: Embed(source="assets/hello.png");
   over-skin: Embed(source="assets/hello-b.png");

Answer 1

[Embed(source="assets/hello.png")]
public var buttonskin:Class;
    b.setStyle("skin", buttonskin);
