Nowadays, it is very difficult to find high-quality, copyright-free pictures at home and abroad, especially for companies or overseas cross-border e-commerce. Most of the pictures on Google are copyrighted. Once a dispute arises, you may have to delete the pictures and pay compensation, or even get into a lawsuit. The following websites all provide free picture sharing services, and the quantity and quality of the pictures are very good. I hope they will be helpful to you.
