* Adds missing width and height attributes to front-end images to help fix the “Ensure images have explicit width and height” warning

* Reduces Cumulative Layout Shift (CLS) by giving browsers aspect ratios up front

* Works on post content, Gutenberg blocks, Elementor widgets, attachment images and post thumbnails

* Dimension lookups cached per URL for a week (in-memory + transient) to keep the filter cheap

* Skips external images, SVGs and data URIs — only local files are measured

* Bulk resize tool for existing Media Library images — scan first, then downscale in place with progress bar and live log

* Automatic sub-size regeneration and stale WebP cleanup after each bulk resize

 

**Orphaned Media Cleanup**

* Scans the Media Library for attachments no longer referenced anywhere on the site — covering images, videos, audio, documents, and archives (configurable per scan)

* Detection covers post parents, featured images, post content (matching by attachment ID, shortcode reference and filename stem so sized variants and URL-only references are caught), and a string-search across postmeta values

* Two-tier confidence classifier — high-confidence orphans are eligible for bulk-delete, review-tier candidates require manual inspection

* Configurable restore window (7, 14, 30 or 60 days, or “keep forever”) with a daily cron purge of expired records

* Staging table records the full attachment post row, postmeta and file manifest before deletion — database records can be restored within the configured window

* Per-attachment exclusions list to permanently keep specific IDs off the orphan list

* For images: deletes the original file, all WordPress sub-size variants, the “scaled” full-size variant and matching `.webp` siblings; for other media types, removes the single attached file

* Pre-deletion re-verification blocks the action if an attachment has become referenced since the last scan

* Live progress bar during scans, batched in 50-attachment chunks to avoid timeouts on large libraries

* Defaults to images-only on upgrade from v1.10.0 — broader media types are opt-in via settings checkboxes

 

**WooCommerce Optimisations**

* Prevent heavy wc-admin React bundles from loading on non-WooCommerce admin pages

* Full backward compatibility with the previous WooCommerce script and style toggles
