Can they just be used as long as there’s no watermark or what? I’m confused about this
If you use royalty free sites like unsplash, pixabay, and pexels they are free to use. But if they have a mark on them you can’t use them.
They need to be free for commercial use.
Even if they haven’t a watermark but they’re from a site that isn’t free, you can’t use them.
But freepik is fine right
