This Is The Free Image License To Look For
I know many members are always asking where to find free images. And by doing a search here you'll find plenty of resources. But even free images can get you in some trouble because many are still copyrighted.
So what you want to look for when sourcing out a completely free image is what's called a cc0 licence - that's Creative Commons Zero Licence.
With a cc0 licence you can do pretty much anything with it. Here's a link to Creative Commons regarding the licence: https://creativecommons.org/publicdomain/zero/1.0/
99% of the images I use I buy or create - but every now and then I do use cc0. And The place I find cc0 licences for images is at https://www.pexels.com/
Here's the link to more information about a cc0 licence if you need it:
Hope this helps
I believe in you
NOTE: Please be sure of the usage available for any images you use - cc0 or otherwise.
