Here's the Gdrive link to a folder that contains desktop wallpapers;
https://drive.google.com/drive/folders/1DAARE15KACXhlEaU2OYaiOR0nvWb8DiN?usp=sharing
They come in 1k, 2k & 4k sizes so make sure to use the appropraite size for your screen. If you have a laptop, it's most likely the 1080p size.
Wallpaper packs will be incrementally updated!
