This plugin simplifies managing media metadata in WordPress. When you upload an image or video, it automatically populates the title, alt text, caption, and description fields using the sanitized filename. Hyphens and underscores in filenames are replaced with spaces, and each word is capitalized for better readability. A settings page lets you choose which metadata fields to update, ensuring compatibility with SEO plugins.
