AS2 Function to Tween Left out of screen and to Tween right

Hi,

I’m creating a image gallery and I have this code when I click on image

html4strict Code:
imageBox[curCell._name]._visible = false;

imageBox[mc._name].fadeIn();
What I want to setup is imageBox[curCell._name] to move out to left while fading out.

And imageBox[mc._name] moving right of the screen to center while fading in…

Could anyone help me to get a tween function to left and a tween function to center from right?

This is Flash Action Script 2 file.

Thanks.
