I have a working UPLOAD example here for anyone who is interested. https://github.com/dtaalbers/FileTransferExample
You can use it how ever you want. Just know that it is not perfect (since FileTransfer is not yet ionic native). I know the jquery used to update the DOM elements with the upload progress isn’t pretty. I’ll take suggestion how to improve it 
.
The pictures will be uploading to a staging API of mine. So know that I can see what you upload 
. To test if the API is working on not you can ping it by GET requesting this url http://services.dtaalbers.com/staging/ping.
