Readme github.com/mattadlard/media-metadata-injector ↗

A WordPress plugin that automatically injects IPTC/EXIF metadata (title, description, keywords, GPS, copyright, etc.) into all media uploads. It can also retroactively update existing images in the WordPress Media Library.

✨ Features

  • Injects IPTC/EXIF metadata into every new image upload.
  • Retroactively apply metadata to all existing images via Tools menu.
  • Stores metadata in WordPress attachment meta if ExifTool is unavailable.
  • SEO-friendly: improves image discoverability and protects copyright.
  • Built with extensibility in mind.

🛠 Requirements

  • WordPress 6.x (should work with WP 5.8+).
  • PHP 7.4+.
  • (Optional, recommended) ExifTool installed on the server:
    • Debian/Ubuntu: apt install libimage-exiftool-perl
    • CentOS/Alma/Rocky: yum install perl-Image-ExifTool
  • PHP functions exec() or shell_exec() enabled (required for ExifTool integration).

If ExifTool is missing or blocked, metadata is stored inside WordPress only (not written into the image file).

  2. Upload the plugin folder media-metadata-injector/ to:
