Ah.  I get it.  You were talking about possible variations on 
cardImage().

The function cardImage() does not do either of those.  It is limited in 
what it does to avoid crashes.

It might be great to have a reliable way to directly get the image of 
some stack that is not current.  However, the cardImage() function was 
designed to get the current card of the current stack.  I am hoping 
there is some way to quietly make some card current, take the image, 
and then go back.  There are issues concerning whether messages should 
be sent.  This works in the current stack (fine for special effects), 
but I have not tried to come up with a method for a card outside the 
current stack; maybe "go invisible", get the picture, "go back", maybe 
with screen locking.
