Unsplash
There is a good reason why Unsplash is one of the most popular stock image websites around. With incredible scenery, portrait, nature and product photographs among others, this expertly curated library rivals premium stock image websites with its high-resolution images. With a well designed search engine it is easy to find the perfect image for your artwork.

Pexels
Rivalling Unsplash for the crown of free stock images, Pexels not only offers high-quality photographs but also free to use video footage. Put together a showreel for your website with HD and 4K footage available through their easy to navigate search engine, follow users you love and download incredible images.
Pixabay
What sets Pixabay apart from the rest of this list is the inclusion of vectors and illustrations in their library. Pixabay has a huge database of images in high resolution and while they may not always be as breathtaking as those found on Unsplash or Pexels, the illustrations and vectors help you to create another layer to your designs.
Usage rights
While all of the above-mentioned sites offer their images for free without restriction under most normal applications, always check the individual usage rights for each site. There may be unforeseen restrictions depending on how you wish to use the image. In most if not all cases you will not be allowed to redistribute or sell these images or claim them as your own work.
