In response to a comment on my previous post, here’s what happens when I plug in my camera and switch it on (in Playback mode) under Ubuntu Linux Dapper:
Then, when I click Import Photos, I get this dialog:
You then just select the thumbnails of the photos that you want to import to your harddrive and click Import. It automatically creates a directory in the location shown using the current date and time.
Much the same sort of thing happens under Windows XP and Mac OS X because they all use the PTP transfer protocol.
