Is money earned from promoting services or programs through my website, when their main page and product page contain images of women without headscarves, halal or haram?

If the advertisement on your website is for something permissible and contains no Shariah prohibitions, then there is no harm in displaying it and accepting payment for it. The fact that the advertisement leads the browser to a page containing pictures of unveiled women does not prohibit dealing with such websites in matters that are permissible. It is incumbent upon theuser to lower his gaze, as these images have become a widespread affliction in many places. Therefore, the presence of such images on the website does not prevent advertising for it, provided that the advertisement itself is for a permissible matter.
