About this plugin
Thumbnail Manager is a safer and more complete media-maintenance workflow for WordPress.
Instead of deleting thumbnails blindly, the plugin now helps you:
- Preview cleanup results before removing files
- Work from focused WordPress-style tabs for Analysis, Sizes, Cleanup, Optimize, Backup, Reports, and Pro previews
- Move thumbnails to plugin Trash instead of deleting permanently
- Create a zip backup of the exact matching thumbnails before moving them to Trash
- Restore trashed thumbnails later if needed
- Process large libraries in batches with visible progress
- Detect orphan thumbnails left behind on disk
- Detect probably unused media items across post content, featured images, and common builder data
- Regenerate missing image sizes in batches
- Review per-size analytics including file counts, storage usage, missing sizes, and orphan counts
- Review recent activity logs and reporting summaries for cleanup, restore, backup, and regeneration workflows
- Disable selected image sizes for future uploads
- Create zip backups for all uploads or a specific year/month folder
- Schedule recurring cleanup runs with configurable frequency, size scope, and folder scope
This release is built for site owners, developers, agencies, and anyone trying to reduce thumbnail bloat without risking accidental data loss.
