I beleive, that the way to do it is using a "hide"-attribute, as Tero
Tilus suggests. This is mainly due to the fact, that grouping is
usable for so many things that we cannot foresee how people want their
images to be displayed.

Sounds strange. I'll look into it in case people don't like my third
iteration patch :-). In the third iteration, multiple parents are
supported, and the bug should thus not be existing there.

I'm impatient as well, but it will take quite some time until this is
stable for real. The concept of grouping is not even properly defined,
and until we have done that it is difficult to write a proper
implementation. But I'm working as much as I can on both, so hopefully
we will see image grouping in KPA some day :-)

Intereseting approach. Actually, I have thought about using a special
"hidden" tag for hiding images, which is something along the same
lines, I guess.

Thanks for your comments and suggestions.
