I have collected these wallpapers over a number of years. This is my entire wallpaper directory for those that want/need them. Created with a slightly modified version of make_gallery.sh script by Jonas Carpay.
I find wallpapers in a number of different locations but good places to check out include Imgur and /wg/. Some of the wallpapers are from other people's wallpaper repos namely Jonas Carpay, MAKC, DT, Christian Chiarulli, and Gavin Freeborn.
Since I got these mostly from sites like Imgur, /wg/, and pixiv, I have no way of knowing if there is a copyright on these images. If you find an image hosted in this repository that is yours and of limited use, please let me know and I will remove it.
