Our jQuery library supports deleting resources on the client-side for a limited time of 10 minutes after being uploaded. After 10 minutes has passed, the image won't be able to be deleted from the client side, only via authenticated API.
When uploading, set the
true in order to tell Cloudinary to return a deletion token in the upload response, use the returned token to delete the uploaded image using an unauthenticated API request.
This is done with the
delete_by_token method (of the jQuery library).
