There should be real copyright, and generally foreign enterprises are more honest (the punishment for intellectual property infringement abroad is very severe). If the website declares that it owns the copyright of the works on the website, and provides the corresponding free downloaded pictures and other works for others' commercial use, he will bear the corresponding legal consequences. If you browse the company (website) and declare that its website works can be used for business, you can use it for business. If it is indeed an infringing work, you can also claim your own exemption at the stage of being sued for infringement. However, how to prove that you are using the copyrighted works obtained for this website requires you to provide corresponding proof. This evidence may be difficult to provide, because once the website does not exist, or the pictures of this website are changed or revoked, it may be difficult to save evidence about your legal use of this website.
I hope my answer can help you.
