The woman admitted adultery and murder. As for the links posted by some members that Iran permits **** and so forth and some of the other ones, they are all fallacious.
To my observation, most if not all news about Iran in the western media are propaganda to demonize Islam and it's principles, Iran's leadership, and her motives, for example the nuclear program. Foreign media reported that the judge freed the real murderer because 'the children have forgiven him' and that's why the judge went after the mother, 'apparently' because all Iranian judges are sadists with a special dislike for women-- this includes women members in the judiciary who are also against their own ***. It reads out as being ridiculous. The addition of insane bit, 'because of a photo' is all that was missing from the piece. The sole purpose and manufacture of the story is to abuse Iran and portray is leaders as being a team of savages who deserve not even the honor to defend themselves or their principles.
It has a likeness to when an Iranian cleric figuratively stated that immodesty causes 'earthquakes' in one's family and the foreign media took off in yet another frenzy-- the whole 'Boob-Quake' exercise which followed was a testament to the partaking womens' own decadence rather than an insult to the cleric.
She has helped murder her husband and she is not an innocent person foreign media portray her to be and moreover she, like most in Iran, was already aware of the legal consequences of such an action.
Anyways, it's amusing for me that 'spiced-up' domestic Iranian district court rulings and convicted Iranians are of so much interest for major news sources and take up which would otherwise be very expensive advertising space.
