Export img from a stack

[Yves COPPE]

Hi list,


I have made a btn from a png file. I've imported the png file as  
control and use it as icon for a button.
I'd like to make some cosmetic change to the img (in Photoshop).
But I have loose the original file

Now, I'd like to export this img from the stack  as a .png file to  
work further in Photoshop.
How can I proceed ?

the img in the stack is ID 2016

Thanks

Greetings.
