Sorry for the mistake and I really didn't realize it. Previously I thought that if an image had no watermark or logo in it, then it was not classified as copyright/plagiarism. I turned out to be wrong, thank you for reminding me and I will immediately replace the image.

As a lesson for me, please explain to me why the picture is not free. So that I can be more careful in choosing images on the internet for the future.

Thank you my Professor @yousafharoonkhan
