This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.

Install straight from GitHub with WP-CLI:

A commercial WordPress plugin I co-built and co-own with ClickWave Co. The plugin covers the full image SEO lifecycle — optimization, metadata management, media library hygiene, auditing, and front-end performance — in a single lightweight package, without relying on external image processing services.

What it does

Image Optimization

Converts images to WebP or compresses them in-place using the server's GD or Imagick library. Every image is backed up before processing. After WebP conversion, all references across post_content, postmeta, options, and Elementor data are updated automatically. New uploads can be processed on-the-fly via the auto-optimize hook.

Bulk SEO Updater

Accepts a CSV with arbitrary column headers, presents a mapping UI so editors can assign columns to alt text, title, caption, and description, then matches rows to WordPress attachments by filename or URL and bulk-updates all fields in one operation.

Media Manager

Three tools in one tab:

  • Unused Image Detector — scans post content, postmeta, widgets, and customizer data to find attachments with no remaining references
  • Duplicate Image Detector — groups attachments by filename and filesize to surface exact copies
  • Folder Organisation — custom taxonomy (imgrank_folder) on the attachment post type for named grouping and filtering

Image Audit

Scores every attachment out of 100 across five weighted SEO criteria: missing alt text (−35), missing title (−20), oversized file (−20), non-WebP format (−15), duplicate alt text (−10). The audit table is filterable by score band, supports inline alt text editing via AJAX, and exports to CSV for client reporting.

Performance Tools

  • Lazy Loading Enforcement — bulk-injects loading="lazy" on all <img> tags across post content
  • Responsive Image Checker — reports images missing srcset attributes
  • XML Image Sitemap — generates a Google-compatible image sitemap served at /imgrank-image-sitemap.xml
  • Schema Markup — injects ImageObject JSON-LD structured data into singular page <head> tags

Technical notes

  • PHP 7.4+ required; tested up to WordPress 6.7
  • Image processing is entirely server-side — no third-party API calls for optimization
  • Account activation calls imgrank.clickwaveco.com/api.php to validate a licence token; a Dev Mode toggle bypasses this for local development
  • All $wpdb queries use prepared statements; all output is escaped at the point of rendering
  • Activation includes a migration path for data from the predecessor ClickWave Image SEO plugin

Installation (local/dev)

  1. Copy the imgrank folder to wp-content/plugins/
  2. Activate from the WordPress Plugins screen
  3. Go to ImgRank → Settings → Account and enable Dev Mode to skip API activation
