Hi all,

I am new to ActionScript. Presently, I am working on ActionScript3.0.
Presently, I am using flash 9.0 and need ActionScript 3.0 code. It's very urgent.


I have a combo-box on the stage with a few items in the combo-box and also have corresponding JPEG/PNG image files. 

My goal is :
I need to display the appropriate image onto the stage based on the selection of the item in the combo-box. So, please I need ActionScript code or procedure to handle this using Event-Handling mechanism of MouseEvent.

These JPEG/PNG files are stored in local OS /System drives.

       I need help.. Please help me.... I am new to the ActionScript and flash environment.

Thanks a lot in advanceā€¦
