Hey @Littlebrother - One important thing to think about when selecting an image is whether the image is licensed or not. Sometimes it is a good idea to pay for usage rights, but free options can be found too. If using  Google Image search as @VanKalkerFarms suggests, you can filter for images by usage rights.

When I do creative work in my free time outside of Square, I use Unsplash to find interesting, high quality free images.
