Stock photos are often a great option for products such as flyers, brochures, or even for images on your website. But before you go spending a bunch of money on some of the bigger stock photo sites out there, make sure to give Pexels.com a try! It’s a free site, so it won't always have what you're looking for, but they have a pretty good collection of photos, so it's always worth a shot! It's definitely the first place I always look when I'm in need of an image!
