Using Tween in a gallery

Hi!
Im having some troubles in flash trying to make a gallery. I dont know much about AS3 but im trying to learn :slight_smile:

What im trying to do is a gallery with 20 different pictures, and 20 different buttons at the bottom to change the pictures.

Im using an image holder for each picture where I load pictures externaly. They all have different instance names (eg, imageHolder01, imageHolder02)

What I want to do is when you click on a button (any of the 20 buttons) that image will come in from the top and stop at the center. Then if you click on any other button the image that is currently at the center of the stage will move out with a tween and the new picture will come in from the top, and so on.

Hope you can understand what I am talking about and be able to help me.

Thanks in advance
