u said promotng websites containng pics or vid of women is not allowed even if the product is halal. sheikh this is literally unavoidable in todays time as most of the sellers/sites if not all use women for display or marketing, music in their product vids. How can muslims earn a living by this way?

Difficulty in finding work does not turn the haram into halal, and Allah Jalla wa 'Ala (the Majestic and Exalted) says, the meaning of which is: "And whoever fears Allah, He will make a way out for him, and will provide for him from where he does not expect" (Surah al-Talaq, ayat 2 to 3). So if you put a link to the website and someone clicks it and sees forbidden things, this is not allowed. And if in your country you can never find a halal job, ask a mufti and explain your situation thoroughly.
