Thanks to Paul at Word Gets Around I have discovered a great site full of royalty free photos to use.
All photos on Pexels are under the Creative Commons Zero (CC0) license. This means you can copy, modify, distribute and perform the photos. The pictures are free for personal and even for commercial use. All without asking for permission or setting a link to the source.
I like to take my own photos where possible but it’s not always practical or affordable to get the shot you need.
I have used one of the photos from the PEXELS website to create my latest palette, feel free to borrow or share.
