Upload Image Using Microsoft Graph REST API - Sharepoint - OneDrive - Using Fiddler

General information for the website: Fiddler REST API call
Description of requirements/features: I have successfully set up the Microsoft Graph API and can upload the example:

https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/item_uploadcontent

----------------------------------------

PUT /me/drive/root:/{item-path}:/content
Content-type: text/plain

The contents of the file goes here.

----------------------------------------

*** My problem is that I cannot successfully upload a PNG image or PDF file. (the file uploads but I cannot preview the png or view the content of the PDF)

I think it is to do with incorrect headers.

I require you to connect using TeamViewer and upload a sample png and pdf using a REST Fiddler PUT (whilst talking over Skype)

The first to impress will get the job.

Regards
Darren
