When you pull an image and it has watermarks like this, instead of having Alamay, Shutterstock, etc., all over, use Google Image search "search by image". Drag and drop that image, to find other instances of the SAME image
You'll usually find that someone already used the exact same image without the watermarks--so just save THAT image and use it.
Similarly, in Facebook, etc., where they have the ads off to the right (almost always a woman with big boobs, regardless of the actual content, such as solar panels ...) and the image is 296x296, drag and drop that image to Google Image Search and look through the results. Almost always you'll find an original that is MUCH larger.
