How to send bluetooth files to a mac?

I took a picture on my Treo and I'm trying to send it via bluetooth to my mac. I already sync it, the cell phone identifies my mac, but on my mac the connection is Off. When I try sending it it just says that it can't. Help please
I do have bluetooth and it is on, when I click on my cellphone description it says Connection: off

at the right of the menu bar on the mac click on bluetooth and turn on. are you sure you have bluetooth?
