Anyway the error you're getting is:

Code:

{"error":"Invalid Media Type"}

That seems to be that even though you're uploading a file with extension .jpg, it's not a real JPEG file, and WhatsApp servers reject it because the format (whatever it is) is not supported.

To verify if it's a real JPEG file (example):

Code:

user:/home/user> file MyDocs/DCIM/20131001_001.jpg 
MyDocs/DCIM/20131001_001.jpg: JPEG image data, EXIF standard

EDIT: If you don't have the file utility installed:

Code:

user:/home/user> sudo apt-get install file
