Im wondering how can I legally use an image from an official website in my YouTube vid. Says the video is about motherboards and I want to take a TUF mobo photo from Asus website as an example, who should I ask for permission or what sort of permission do I need to use it "commercially" ?
You need to find out who the copyright holder is. Either the photographer or as likely in this case, Asus. Then you work out a licensing contract with them.
