Yes, you need authorization from the brand to list goods on AliExpress. You need to prepare authorization letters and other relevant qualifications according to official requirements, take photos of the size and upload them. You can only upload the goods after the official review. If you list them without authorization, it will definitely infringe copyright! As for pictures, if they are provided by the brand, then there is no problem. If you steal pictures from other peers, it is also an infringement.
