Is a husband entitled to prevent his wife from publishing promotional pictures of a presidential candidate (Sheikh Abu Ismail) online, under the pretext of jealousy and fear of discord, given the wife's refusal?

Scholars differ on the ruling concerning a woman looking at a non-mahram man without lust or fear of fitna (temptation), and the more preponderant opinion is that it is permissible in such a case. If the husband has forbidden her from publishing pictures of non-mahram men, then she must obey him, as obedience to the husband is obligatory in matters pertaining to the woman's chastity and the husband's protective jealousy over her.
