There are many websites where you can find photos, but the quality isn't always the best, stock photography sites charge a fee, and images at Flickr often come with licenses that restrict how you use an image. Here's how Unsplash is different:
Over 300,000 free (do whatever you want) high-resolution photos brought to you by the world’s most generous community of photographers.
All photos published on Unsplash can be used for free. You can use them for commercial and noncommercial purposes. You do not need to ask permission from or provide credit to the photographer or Unsplash, although it is appreciated when possible.
More precisely, Unsplash grants you an irrevocable, nonexclusive copyright license to download, copy, modify, distribute, perform, and use photos from Unsplash for free, including for commercial purposes, without permission from or attributing the photographer or Unsplash.
Even though credit isn't required, Unsplash photographers appreciate a credit as it provides exposure to their work and encourages them to continue sharing. A credit can be as simple as adding their name with a link to their profile or photo ...
Unsplash images have a Creative Commons Zero license that lets a person download, copy, alter, and distribute a photo for free ("no rights reserved".)
