Painting on an image in a group?

Looking through my mails after just having returned from a few days 
"time-out" for recreation I notice this "Painting on an image in a 
group?"-discussion:

Some time ago we had a discussion on the Metacard list concerning 
related problems of painting and drawing on images inside a group. The 
solution found was to temporarily move the image outside the group, 
apply the changes to the image, and then move the image back into the 
group. The following script  demonstrates the implementation of this 
principle (button "distortions: choose shape" contains the script that 
applies changes to the image):


on mouseUp
  set the imagedata of img x to the imagedata of img x
  set the relayergroupedcontrols to true
  put the layer of img x into tlayer
  set the layer of img x to top
  send "mouseup" to btn "distortions: choose shape"
  set the layer of img x to tlayer
  set the relayergroupedcontrols to false
end mouseUp

So an alternative approach to Scott's proposal of creating and using a 
second image would be just to move the image outside the group 
temporarily and then put it back into the group after applying the changes.
