The best one i found.

 

For making the wallpapers show at random, you can set Windows to put them on a random slideshow and set how frequently you want them to change backgrounds.

I have it set to playing pictures from one folder (for wallpapers) and changing every 30 minutes. Also it will show a different picture for each monitor I have (usually two, but sometimes 3 if I plug in the TV).

 

I have almost 500 wallpapers set in rotation. I could try to share them, but there's too many and my internet is shitty. Honestly I'd say just trawl the internet for really high resolution pictures that you like and look like they can be cropped to 21:9 without losing too much. As for cropping, I'd say the easiest way would be to use Gimp to set the canvas size to 21:9, then slide the image around until the crop is good. There will be better apps, but I'm not aware of them as google just brings up a bunch of online croppers.
