Is it possible to send image not via base64_encoded_data? Is so, let us know, in what way.

Please, help us.
Thanks in advance

@MomotenkoNatalia , @kandy , I am also facing same issue while adding images to already existing item on Magento 2, is there any update on it? Also is there any API to upload images on Magento2 so I can link it later to existing items?
