XMLRPC Image Upload

Hi.

I am trying to upload images to WordPress via XMLRpc. A new image is generated each time I run my code but I see an empty image in my Media Library. I have tried to use a bit string (1010101), base64 encoded string and bitmap but nothing seems to work. In the XML-RPC documentation (https://codex.www.ads-software.com/XML-RPC_WordPress_API/Media#wp.uploadFile) the format of the “bits” field isn’t clear. It just says “bit data”.

Thanks in advance.
