Currently, you can upload a single or multiple existing images from your WordPress Media Library.
You should go to your WordPress Media Library and:
- Either hover a specific asset you would like to synchronize and click on Push to Cloudinary.
- Or select a list of assets you would like to synchronize then select the Push to Cloudinary bulk action and click on Apply.
The images will be uploaded to Cloudinary while the content of all associated posts and pages will be automatically updated to point to Cloudinary's CDN URLs.
