dear anon.,
you are very astute to point out the shameful lack of hadzic kid photos. the reason for said omission might be explained by two possible scenarios:
1. their mother doesn't let them do anything of interest.
and/or
2. when their mother does let them do something of interest, she forgets that she owns a camera.
thank you for your concern. rest assured, we've got our best people working on the problem.
