[gnome-shell-ext] Getting a different lock screen wallpaper daily

[zp Z <zhang9zp970 gmail com>]

Hi everyone here!

    Do you think it is a good idea to make some changes to the gnome lock screen wallpaper?

     One day, I felt tired about the same lock screen all the day and wondered if I can have a Windows Spotlight lock screen on my gnome desktop. Thus, I wrote a small python program to catch a Bing wallpaper everyday and set it as my lock screen. Here is the project: https://github.com/zhangzp9970/GnomeBingLockScreen.

     And my question is, how can I make a gnome shell extension instead of adding a command in start up applications. Do I need _javascript_?

    Also, can you give me some ideas about how to improve this project?

                                                                                                          Thanks
