With Upload method, you can upload images to the Image Search system. This method is intended for upload of small numbers of images. For more information, see Upload images
With OSS Import method, you can import images from OSS. This method is intended for upload of large numbers of images. To do this, you must activate Object Storage Service and then add the required RAM role to your account. For more information, see Import from OSS.
