Docs: please provide example of image upload (PATCH)

[sarn0ld]

After debugging and trying around for several hours I now found out how to upload images (e.g. for a news_item).
Other than stated in the documentation the json property should be called "image", not "file".
Maybe somebody needs this later, so I note it down here for future reference... here is a working Example:

{ 
  "title": "TestTitle1",
  "description": "TestDesc",
  "text": {
    "content-type": "text/html",
    "data": "TestText",
    "encoding": "utf-8",
  "image": {
      "data": "/9j/4A***BASE64-Encoded-Utf8-String***A//Z\n",
      "encoding": "base64",
      "filename": "image.jpg",
      "content-type": "image/jpeg"
    }
  }
}
