Image sending not really working in 0.0.7, maybe I'm doing something wrong?

[Pachuchi420]

I already posted this as a comment on one of the issues posted. I'm posting again as we can maybe discuss things here in a more clear manner . As stated before I was waiting for version 0.0.7 to get image uploads going but alas it doesn't work. Granted I don't get any error messages but nothing really happens. Text messages work fine, but other than that its still broken for me...

Here's a quick demo to show what I mean (link for better view):

Attached is the project that I'm using. On version 0.0.6 I would get a 415 HTTP error but now this is not even displaying anything?
whatsappTest.zip

It's really quite weird, as the code I wrote seems clean enough but whenever I click to send the image test nothing really happens, back in release 0.0.6, I at least got some kind of error before but now nothing. Maybe I'm doing something wrong? But for the life of me I can't figure out whether its my implementation or something else?
