When I moved my blog into Drupal 8 the summer of 2016 I used the theme Bootstrap Clean Blog which have a nice big photo on top of every article. That increased my need of good stock photos, so i started out to look for good resources. This is a list of the sites I found and use for all my needs.

Sites with photos that need no attribution*

A site created by someone whose photos was rejected by the big stockphoto sites. Lucky for us, that only spurred him on to do something about it. His project became picjumbo.
