Manage large adaptive (mobile-ready) images and automatically apply them to areas on your WordPress site as backgrounds. 
Pull beautiful photos from Unsplash using the in-built browser, or supply your own images from uploads and supplied URLs.
Usage
Once activated, go to Appearance > Nice Backgrounds. You can create one or more ‘sets’ of background images with 
different settings.
Note: This plugin typically deals with resizing very large images, if you’re having problems make sure your memory limit 
is sufficiently high enough to deal with some occasional heavy lifting.
Note: PNG images that are either very large or are 24-bit can be problematic. The exact details of this are yet to be 
determined.
<h3>Credits</h3>
Just the other day I read a fortune cookie that said something about giving credit. I threw it away, but here is a 
list of stuff I looked at to get some ideas of what to do for this plugin:
