+draphyOS includes a wallpaper management command that updates desktop, lock screen, and login screen:
 
-Change wallpaper:
 ```bash
-feh --bg-fill /path/to/image.jpg
+set-wallpaper /path/to/image.png    # Set new wallpaper
+set-wallpaper --current             # Show current wallpaper paths
+set-wallpaper --reset               # Reset to default draphyOS wallpaper
 ```
 
-The wallpaper is set automatically on login via `~/.xprofile`.
+**What it does:**
+- Copies image to `~/.config/wallpaper.png` (desktop/lock)
+- Copies to `/usr/share/backgrounds/draphyOS/` (login screen)
+- Clears lock screen cache (regenerates on next lock)
+- Applies immediately to desktop
+
+**Supported formats:** PNG, JPG, JPEG, BMP, WEBP
+
+**Manual method (feh only):**
+```bash
+feh --bg-fill /path/to/image.jpg
+```
+Note: This only changes the desktop, not lock/login screens.
