Blackberry Messenger Default Image Size

Jut got a Blackberry Bold 9780 from my brother. He insist me to use BB so I can communicate with my family in Indonesia. We already have Yahoo Messenger, SMS, Facebook chat, Google talk, Skype, and even Facebook chat, why do I need one? After playing a little bit with it, it turns out quite fun using a Blackberry. Just to remind me that Blackberry Messenger default image size attachment is 480 x 360 pixel. Now I can't concentrate, busy checking message, email and bbm from my new BB....sigh...

Below is a photo of my grandson, sent by my nephew from the Blackberry Messenger, check out the image size.
