A PowerShell script that automatically downloads the latest satellite image from Himawari-8 (Japan's weather satellite) and sets it as your desktop wallpaper. The image is fetched based on the current UTC date and hour.
- Fetches satellite images from the Himawari-8 satellite.
- Downloads the image based on the current UTC date and time.
- Saves the image to a specified directory on your computer.
- Automatically updates your desktop wallpaper.
- Logs each wallpaper change, including the image size and any errors, to a log file.
- PowerShell: The script is written for PowerShell (available on Windows by default).
- Internet connection: The script fetches satellite images from the Himawari-8 API, requiring internet access.

What the script does:
- Downloads the latest satellite image based on the current UTC date and hour from Himawari-8.
- Saves the image in a subdirectory under
Pictures\himawari\yyyy\MM\dd\HH.png. - Sets the downloaded image as your desktop wallpaper.
- Logs all activities (successful downloads, errors, etc.) to a log file (
wallpaper_change_log.txt).
- Log File Location: The log file is saved under
$env:USERPROFILE\Pictures\himawari\wallpaper_change_log.txt. You can modify this path in the script if you prefer a different location for the log. - Minimal Image Size: The script only downloads images if the
Content-Length(image size) is above the defined threshold (5,000 bytes by default). You can change the$minimalContentLengthvariable to set a different threshold.
- No image downloaded: If the image is too small (below the minimal size threshold), the script will log this and not update the wallpaper.
- Network Errors: If there is an issue downloading the image, the error message will be logged.
