v1.0.1

Added

• Multisite Network Support: The plugin now supports multisite networks, including those using a single media library for site ID 1. If the alt text is not found in the current subsite's media library, it will check the main site's media library.
• Enhanced Documentation: Updated the README file to include details about the new multisite network support and usage instructions.

Fixed

• Alt Text Retrieval: Improved the logic for retrieving alt text to ensure it checks both the current subsite and the main site in a multisite network setup.
