Is it permissible to work in e-marketing for dental clinics if it involves photographing and publishing images and videos of unveiled female doctors, or images of immodestly dressed female patients?

There is no objection to marketing and advertising permissible services and benefits and taking a fee for them, provided that nothing is added that is forbidden to see or hear, such as the display of women's nakedness. If the marketer is able to avoid photographing immodest women and objectionable things, then there is no blame on him; otherwise, he is complicit in the sin of spreading forbidden images.
