The User Guide is often overlooked. A pretty good explanation of groups 
and backgrounds, and their differences and behavior, begins on page 107 
of the guide. The User Guide can be accessed from either the Help menu 
or from the Resources icon in the toolbar.

This may be superstitious behavior based on an occasional delay when 
loading multimedia into player objects. In a player, it is sometimes 
necessary to set the filename to empty before resetting it to a 
different video. But for image objects it isn't needed, and you can omit 
that instruction.

I have a stack that does exactly what you're doing; it loads a different 
image into a grouped image object every time the card changes. It works 
fine by just replacing the content with a new image.
