[*]Create a new layer, give it the name border and select the rectangle tool. Now, roughly draw a border around the image. The width, height and position will be set through ActionScipt, so you can place it anywhere and give it any size you want.[/COLOR][/LIST]Does anyone know wich tool his using to make a border?

Thank you
