How to install?

1. install ImageMakick (sudo apt install imagemagick or sudo yum install ImageMagick)
2. Take a random image and rename it to "bing.jpg"
3. Go in system settings -> Startup and Shutdown -> Login screen (SDDM) -> (behaviour if it appears) and set that image as background
4. Save that script in /etc/init.d/ and make it executable (sudo chmod 755 download_bing.sh)
5. You may want to edit "downloadTo" if your theme isn't Breeze, but the "bing" image should be in the folder you set (in "downloadTo", "bing" is the image, not a folder)
6. Run the script and see if it works (it may not, I made it for my own personal computer, but I don't see why it should not)
7. Run sudo ln -s /etc/init.d/download_bing.sh /etc/rc3.d/S02download_bing (creates a symbolic link to a folder where it will be run on startup)
8. It should be done!
