Carbon Based Studio Image Controller gives you a unified workflow for uploads, intermediate sizes, and nextgen delivery. Generate WebP and AVIF into wp-content/cbs-nextgen/, scan coverage, bulk-regenerate thumbnails, resize on upload, and optionally convert TIFF uploads without juggling multiple plugins.
Settings live under Carbon Based > Image Controller, alongside other Carbon Based Studio plugins in the shared admin hub.
Key features
- WebP & AVIF nextgen - optional rewrite rules for capable browsers; originals stay in place.
- Conversion & thumbnail coverage scans - see gaps before you run bulk jobs.
- Bulk regeneration - rebuild sizes and nextgen files in admin batches.
- Disable unused image sizes - reduce disk use on large libraries.
- Upload resize - cap max width/height at upload time.
- TIFF support - allow TIF/TIFF and convert to JPEG (Imagick required).
How it works
- Install from WordPress.org and activate the plugin.
- Open Carbon Based > Image Controller.
- Enable WebP/AVIF and quality on the NextGen tab.
- Run Conversion Coverage to find missing nextgen files.
- Bulk-generate and regenerate thumbnails as needed.
- Fine-tune upload limits and disabled sizes on other tabs.
Use cases
- WooCommerce catalogs - smaller product galleries and faster category pages.
- Media-heavy blogs - control intermediate sizes and remove unused thumbnails.
- Migrations - scan after import, then bulk-regenerate to match new rules.
FAQ
Where are nextgen files stored?
Under wp-content/cbs-nextgen/, mirroring the original path under wp-content/.
How do I view the original image while testing?
Append ?original to the image URL to bypass nextgen rewriting.
