Image brokes when I upload files with http

[daniilkurlovich]

Hi, i got a problem with upload images in dropbox. Check my code

Other files are transmitted and i can read after upload in dropbox.

But in images files written 'This file is not available for preview.'

You're using the "files" parameter in the Python requests library "post" method, which seems to be for "multipart encoding upload". The Dropbox API /2/files/upload endpoint does not use multipart encoding upload, however, and instead just expects the raw file content to be sent in the request body (to match the "Content-Type: application/octet-stream"). 

Update your code to use the "data" parameter to send the file data in the request body instead.
