Best all-in-one solution for free/cc/public domain images/photos/etc.

The recent addition of Openverse really makes this one of the best (if not the best) plugins for adding free / creative commons / public domain images/photos/etc. libraries/services to your site.

Some of the image libraries can have limited offerings so this providing as many of these libraries as possible to then pull from really helps with that situation to be able to find the best asset you’re looking for.
