InputfieldSplashAndGrab
This module attaches a search input to selected image fields that lets you search and download images from Unsplash.
(Unsplash is a stock photo service where you can download images for free and use as you wish. No strings attached.)
You can search by string, colors, orientation/crop and order by relevance or time published
I find Unsplash useful both for placeholder images when building sites but also as a time saver for editors if they don’t have any images at hand, just search, download and publish.
Thanks to Apesia for building the FlickrInputField Module and Robin for AddImageUrls, took a lot ideas and code from those modules.
