+### Changes Made in `mkbsd.js`

+- **Local JSON Source**: The script was updated to read from a local `images.json` file instead of fetching data from a remote URL. This allows you to have full control over the data source.
+- **File System Operations**: The script now uses Node.js's `fs` module to read and parse the JSON file directly.
+- **Image Download Logic**: The image download logic was adapted to extract the artist's name and image URLs from the local JSON structure, ensuring the images are saved in artist-specific folders.
