One of the more common requests I get is to share one of the images I have as a wallpaper or decoration in a video, so here's my entire wallpaper folder.
Just FYI I get most of my wallpapers from /wg/.
I sort things into really general folders, with an Unsorted folder for those I haven't gone thru.
Since I got these mostly from /wg/, there's a possibility that some might be legitimately copyrighted. If you see an image that is yours and of limited use, tell me and I will remove it.
