Western advocates of Isis, such as Anjem Choudary, often emphasise the group's social welfare aspects over its violence.
The logic of promoting this side to life under Isis is clear: The group aspires to establish a state. To do so, it needs women and children as well as men. Plus, reporting from the Washington Post's Liz Sly and others has shown that these aspirations do not appear to be materialising. Images of women enjoying a normal life under Isis may be an attempt to undercut that perception.
Of course, the images shared on social media may not always show the reality. While some women who joined the Islamic State were given positions in the al-Khansaa brigade, a group that functions as morality police, most women, in fact, are expected to assume a docile role.
Last year, a report by the United Nations found there were severe restrictions on women living in Isis-controlled territory, with women "confined to their houses, excised from public life". A document attributed to Isis that was released this year said there was "a fundamental necessity for women to have a sedentary lifestyle". And, of course, there have been numerous reports of violence against women perpetrated by Isis fighters.
Mia Bloom, a professor of security studies at the University of Massachusetts at Lowell, says images shared by women living under Isis may be designed to entice foreign women to join the group, giving them an unrealistic impression of life for females in the "caliphate". But the images may also be designed to entice another audience: men.
"Recruiting women, aside from potentially doubling the resource base, has the effect of goading men into participating," Bloom explains. For men, the message is obvious, she says: "You're not coming here, so the women have to pick up the guns."Washington Post
