desktoppr has a learning a few new tricks that will make it simpler to use it in managed environments.
When used with the manage verb desktoppr now reads settings from the com.scriptingosx.desktoppr preference domain. This allows Mac admins to manage desktoppr with a configuration profile.
When the setOnlyOnce key is set to true in the profile, desktoppr will not re-set the desktop picture/wallpaper on a re-run, even when the user changed it.
You can also give a URL instead of a local file path for the image file, then desktoppr will try to download the image file from that URL and use that.
Read the documentation for v0.5b.
