Script for changing the lock screen wallpaper on Windows 10 AME.
You can download the script by going to the latest release and downloading
lockscreen-img.bat from the Downloads section.
Alternatively, you could clone the repository:
git clone https://git.ameliorated.info/LoganDark/lockscreen-img.git
To run the script, simply drag and drop an image file onto it. You can also run it from a CMD prompt like so:
C:\Users\user> "Downloads\lockscreen-img.bat" "Downloads\ame_wallpaper_1440.bmp"
Since the Creator's Update, JPEG files have been saving as .JFIF instead. You will have to rename them to use them with the script. The script also will not accept any of the more exotic extensions for JPEG or BMP files, so you may have to rename the file if your extension is nonstandard.
This is a preventative measure so you don't accidentally replace your wallpaper with a non-image by dragging over the wrong file.
