What is the ruling on using pictures of women with their hair showing or in gyms to help understand websites, knowing that these websites are for non-Muslims?

A woman's hair is 'awrah (private/uncoverable) by scholarly consensus. It is not permissible to use her image if her hair or any other part of her 'awrah is uncovered. It is forbidden to place pictures of women in sports halls because they often reveal what is unlawful to reveal, whether the location is for Muslims or others. This is because advertising with such images contradicts the rulings of Sharia and the values of religion.
