Readme github.com/mav1101/image-seo-manager ↗

A single-file WordPress plugin to export and bulk-update image alt text and titles in the Media Library.

Features

Export tab

  • Lists all images: thumbnail, file name (from _wp_attached_file), alt text, title, attachment ID, upload date.
  • Used On column: every published page/post/CPT using the image (featured image, post content, Elementor data, galleries), as links; Elementor templates link to their edit screen. Usage data is cached for 1 hour; use Refresh usage data to rebuild.
  • 50 per page, with search (file name, alt text, title) and "Missing alt text only" / "Unused images only" filters.
  • Export to CSV downloads all images as image-seo-export-YYYY-MM-DD.csv (UTF-8 with BOM, columns: File Name, Alt Text, Image Title, Used On, Attachment ID). Streamed through admin-post.php with a nonce check; nothing is saved on the server.

Bulk Update tab

  • Upload a .csv/.txt file or paste tab-separated rows from Google Sheets/Excel.
  • Columns are detected by header name (case-insensitive, any order): File Name, Alt Text, Image Title. Other columns are ignored.
  • Rows are matched by file name: folders ignored, case-insensitive, extension optional, and WordPress suffixes (-scaled, -1, -300x200, ...) are tolerated.
  • Empty cells never blank out existing values.
  • Options: "Overwrite existing values", and "Update all" / "Skip and flag" when a name matches several images.
  • Preview is a dry run with a colour-coded status table and summary counts. Apply Changes (with a confirm dialog) updates in batches of 100, then offers a results log CSV.

Installation

  1. Download this repository as a zip, or zip the image-seo-manager folder so it contains image-seo-manager.php.
  2. In WordPress: Plugins → Add New → Upload Plugin, choose the zip, then Install Now and Activate.
  3. Open Media → Image SEO Manager.

Requires WordPress 5.0+ and PHP 7.2+. Users need the upload_files capability.

Notes

  • WordPress usually sets an image's title to its file name on upload, so with "Overwrite existing values" unchecked most titles will be left unchanged.
  • Back up your site (or export a CSV) before applying bulk changes; updates are not automatically reversible.
  • Preview jobs expire after two hours.
