I did download the Importer Ning to BuddyPress plugin

Hi

I did download the Importer Ning to BuddyPress plugin and try to use it.
Please explain me how to import my memberships.

I see in your example that you import all the details in the CSV file and the profile picture.
Where I should locate the CSV file, and where I should locate the folder of the members which I did downlod with the NingNetworkArchiver application (the profile picture is there)?

Thanks Oved
