What is the ruling on profiting from YouTube channels that display advertisements which may contain images of unveiled women, and is it permissible to earn from showing these advertisements?

As long as the advertisement and promotion were for permissible goods, it is not forbidden to benefit from the money earned. However, it is not permissible to publish an advertisement that includes a picture of a woman who is immodestly adorned, because it is a reprehensible act and leads to sin.
