This is possible, but you will have to set the id of the used and 
referenced images to some (incredibly) high numbers (at least 6 digits) 
manually.
(set the id  of image "yourimage" to 1000001)

Then use buttons to display that image.

The engine will search all open stacks for that icon of a button.

I did it before and it works.

When the backgroundbehaviour of that group is true, then you can place a 
group (with images)
on every card without ending up with zillions of copies of that image.

If not, then there must be a bug somewhere.

Groups are meant to behave like one object (with backgroundbehaviour set 
to true, if i did not mention this before ;-)


Hope that helps
