how to change the background of spinfinity theme in fedora plymouth

To change the background of the Spinfinity theme in Fedora Plymouth, you will need to follow these steps:

Open a terminal.
Navigate to the /usr/share/plymouth/themes/ directory by running the following command:
```
cd /usr/share/plymouth/themes/
```
Make a backup of the original Spinfinity theme folder by running the following command:
```
sudo cp -r spinfinity spinfinity_backup
```
Open the Spinfinity theme folder by running the following command:
```
sudo nautilus spinfinity
```
This will open the file explorer with root privileges.
Inside the Spinfinity theme folder, locate the spinfinity.script file and open it with a text editor.
Look for a line that starts with background_image or wallpaper_image. This line specifies the background image used in the theme.
Replace the path of the existing background image with the path of your desired background image. Make sure the new image is in the correct format (e.g., PNG).
Save the changes to the spinfinity.script file and close the text editor.
Close the file explorer.
Update the Plymouth configuration by running the following command:
```
sudo plymouth-set-default-theme spinfinity
```
Reboot your system to see the changes take effect.
```
sudo reboot
```

After rebooting, you should see the new background image in the Spinfinity theme during the boot process
