For anyone needing an image to help tell their story online, Creative Commons Zero (CC0) is an option to explore. There are a number of types of CC licenses and you need to be aware which one you are downloading. For many small businesses using CC0 images to spruce up their site is a great option due to their price. Free, plus any donation you feel compelled to share with the photographer.
Take the time to research this type of image for your online marketing needs. It might be worth your effort.
