I love this resource –
You download and install it as a browser plugin on Firefox (not sure if it works with Chrome or others).
It then automatically shows up in your WordPress admin panel and recommends relevant photos, articles, tags, Wikipedia links, Amazon products (you can use your affiliate ID), and more. It’s customizable so it only shows/recommends what you use.
Primarily I use it for photos, see above.
