Does the camera on the Tour have a timer?
Also, how can I send more than 1 picture at a time?
There is not a timer for the camera. However you can find a 3rd party app for a timer. Do a search for Blackberry Camera Timer and you will find something.
Yes you can compose a MMS message and attach multiple pictures. Just remember the size of the pictures might be large, so it might be better to send as an email.
