Unsplash.com: free photos
Millions (!) of free images of all kinds can be found on the website Unsplash.com.
A unique site where licensed images may be used free of charge for non-commercial and even commercial purposes. This thanks to generous contributions from many photographers worldwide. An initiative that we are happy to participate in.
It is of course also nice to see that some of your photos have been viewed no less than 650,000 times around the world and one of them has been downloaded more than 6,500 times.
Please be careful! There also are photos on Unsplash that you have to pay for and you may end up on an affiliate site, where you also have to pay.
