What is the ruling on pictures of parties and brides, and their viewing by men other than the husband?

It is forbidden to photograph women at wedding parties if it is known or highly probable that their pictures will be seen by non-mahram men. This is because it assists in what is forbidden and spreads the causes of temptation (fitna) and corruption. It is obligatory to be cautious about this, and men must prevent it to safeguard their honor.
