Sometimes the hardest part about finding a good image, reference or texture is finding one that is not copyright protected. Here is a list of my favorite free sites and you can even use the images for your commercial work.
- morguefile.com - Creative commons site where images are donated "for creatives by creatives". They boast over 350,000 images in their library.
- pixabay.com - All images and videos on Pixabay are released free of copyrights under Creative Commons CC0. You may download, modify, distribute, and use them royalty free for anything you like, even in commercial applications. Attribution is not required. They have a whopping 1M+ images in their library!
- unsplash.com - "Beautiful free photos gifted by the world's most generous community of photographers." Creative commons zero license.
- freeforcommercialuse.net - This site is new to me. License is for images in the public domain.
- pexels.com - Simply, all images on pexels are under the Creative Commons Zero License. You can use them for any legal purpose.
