If you scratch under the surface there's always same BS " No commercial use is allowed, you will need to contact the image Author/Owner for permission or information about any commercial use, In case there no author or or any licence is indicated thatís because we donít have the information, and that doesnít mean itís free for commercial use."
Is using an image here really "commercial use"? No one ever paid me for an image!
Of course BS may be a pro! I don't know!
Of course that may be BS too!
