UILoader and next-button

Question

Hi!
I use UILoader to load pictures from folder. Example 1.jpg, 2.jpg etc. I have just buttons to browse pictures. Button 1 loads picture 1 etc.
Now I need next and back buttons to browse pictures. Is it possible to do? How?
Here is code I use:
var photo:UILoader = new UILoader();
var defaultPIC:URLRequest = new URLRequest("1.jpg");
photo.load(defaultPIC);
picbox.addChild(photo);
photo.scaleContent = false;
photo.maintainAspectRatio = true;
panel_mc.panelInner_mc.btn_01.addEventListener(MouseEvent.MOUSE_UP, pic1);
function pic1(event:MouseEvent):void{
    picbox.removeChild(photo);
    photo.load(new URLRequest("1.jpg"));
    picbox.addChild(photo);
panel_mc.panelInner_mc.btn_02.addEventListener(MouseEvent.MOUSE_UP, pic2);
function pic2(event:MouseEvent):void{
    picbox.removeChild(photo);
    photo.load(new URLRequest("2.jpg"));
    picbox.addChild(photo);

Answer 1

I have my Quiz Manager setup to Allow backward movement and
to Show progress. I have not enabled any other settings on the Quiz
tab. On the Options Tab, I have under the If passing grade, jump to
"go to next slide" and under If failing, I have Allow user 2
attempts and Jump to "go to next slide".
For each slide I have the same setup under the Options tab as
what I have noted on the Quiz Manager.
I have published and tested the movie. I'm still unable to
use the Back and Next buttons.
Any other suggestions?
Thank you,
