For my laptop I decided to change it to a car that I have been eyeballing over for awhile. Make Mitsubishi great again!
The default windows 10 one. Normally I always set a custom desktop background but this one is so nice I actually like it.
I found a link to this guy when browsing a car forum. He has all sorts of car pictures, I particularly like his Saab photos, all of them are high quality and most of them are good shots. Here
I think I got most of them from Imgur but I also picked around to get matching styles so its more than one source so I'll just upload all of the backgrounds from my slideshow folder here.
