 Note: Apple used to call the macOS background image 'desktop picture' until macOS 13 Ventura, when they changed to be the same as in iOS: 'wallpaper'. This documentation might use either term.

 Note: setting the background color does not work in macOS 14.x. See [issue #22](https://github.com/scriptingosx/desktoppr/issues/22).
 
+## Downloading the wallpaper image file
+
+When you give a URL to an image file as the argument, `desktoppr` will download the file from the URL and set it as the wallpaper.
+
+```
+$ desktoppr https://raw.githubusercontent.com/scriptingosx/desktoppr/profile/examples/BoringBlueDesktop.png

+The downloaded file will be stored in `~/Lubrary/Application Support/desktoppr/`.

+When the download fails, the wallpaper will not be changed. If the downloaded file is not an image file, the wallpaper will revert to the system default.

-Since the `desktoppr` tool also sets user preferences, you still need to pay attention that it runs as the user. A LaunchAgent or a solution like [`outset`](https://github.com/macadmins/outset) is a good choice to manage this. Alternatively, you can [run the command as the current user from a root script](https://scriptingosx.com/2020/08/running-a-command-as-another-user/).

-## Managing the desktop picture/wallpaper with desktoppr
+## Managing the desktop picture/wallpaper with a profile
 
 When you run `desktoppr` with the `manage` verb, it will read the settings from the `com.scriptingosx.desktoppr` preference domain. You can set these settings with the `defaults` command or, preferably, by pushing a configuration profile from an MDM server. 
 
 The idea is to run `desktoppr manage` with a LaunchAgent plist at login and/or at regular intervals. You can find [a sample LaunchAgent plist here](examples/com.scriptingosx.desktopprmanage.plist). The sample LaunchAgent will run `desktoppr manage` at login and every three hours (10800 sec). You can build a pkg that installs the desktoppr binary, the LaunchAgent plist and an image file very early in the deployment workflow and then desktoppr sets the desktop background when the user reaches the desktop for the first time.
 
-For Ventura and higher, binaries and applications run by LaunchAgents need to be approved with a `com.apple.servicemanagement` profile so they appear as managed in the login items section in Settings.app. The above sample configuration profile contains those settings, as well.
