Is working as a manager for a website that publishes pictures of unveiled women permissible or forbidden (halal or haram), and what should a wife do if it is forbidden and her husband is not convinced of that?

If the magazine publishes pictures and intentional prohibitions and considers them a main focus, then it is not permissible to assist in their publication and production, based on the Almighty’s saying: "And do not cooperate in sin and aggression." For means follow purposes; thus, the means to the forbidden are forbidden. However, if the pictures are unintentional, such as news photos, there is no harm in the work; because what is forgiven in a subsidiary is not forgiven in a principal.
