How do I upload photos from blackberry bold to mac?

I have a mac os x, and a blackberry bold 9790.
I want to get photos from my blackberry on to my mac.
I plug it in and in my find I have 'blackberry 1' and 'blackberry' in the USB port thing. If I click on blackberry it has a folder 'blackberry' and 'tmp'. Blackberry contains the folders 'pictures', 'podcasts', 'videos' etc, however if I click on picture ONLY my screenmunches are there....
What do I do?
Do you have this same layout with blackberry and blackberry 1 etc
Please help
Thanks!
