Preloader tutorial problem

I’ve just tried this Preloader but couldn’t get it working as it shows in the example:
[color=#003366]Reusabel Preloader Using MovieClipLoader[/color]

[color=black]The error occurs when I view the swf file online. All images preload when I click on the buttons, except the default image won’t appear. [/color][color=black]There should upload a default image when visiting the page, just like on the tutorial example.[/color]

[color=black]I’ve also tried it with the tutorial example file but it gave the same negative result.[/color]

Anyone knows what I’m forgetting?
