If you're looking for a athlete, celebrity, or anyone/anything else that you wouldn't have your own photo of, follow the steps below to find the perfect photo:

We would recommend trying to find an image with at least 2800 pixels within the height of the subject matter within the image.
The best way to do this is to search Google, then select "Images," next click "Settings" and then select "Advance Search" Then look down the page to area that says: "Narrow Your Results By..." the Image Size selected should be larger than 4 MP. This may help you get results that are larger and more likely able to be used.
