When you are using pictures from the internet you cant use all of them. Finding a picture is more complicated than people think. There are certain requirements you need to use when you are searching for pictures. When you are using Google the way that you can use an image is that you have to go to tools and then you have to click on usage. Once you have clicked usage then you have to click on one of the four options, the option I suggest is labeled for non-commercial reuse. I think that Bing is the easiest to use for images because all you have to do is go to images and press license, the one that you should press is free to use and share. Those are two of the easiest ways to get pictures with the right usage.
