I use imgur to host my images for backgrounds.

I use a lesser known site called Imgbox. Works well c:
I try not to think. It interferes with being nuts.
What said, imgur is nice because it can host really big images. Back when I was using other sites I'd always have to resize things to be smaller or lower quality files, but I never have to do that with imgur. I wouldn't recommend it as social media, but as a free image host it's top notch. :)
