Sending multimedia messages will take a while to implement. Receiving pictures (without sending) will be implemented soon (in like 2 or 3 weeks).

Right now I'm working in contacts synchronization, after that I'll dedicate exclusively to smileys I guess, and then reception of pictures. Sending them is another topic, which is a little bit complicated (I still have to hack the method of uploading a picture to a Whatsapp server).
