Access Media - what what?

[Kweli]

On my WebsiteBaker Page there are three Users and one Admin. The three Users have got personal pages. When you're not logged in or you are another user, and you access this pages, you get an error-message. That's nice. BUT!
The users also need a personal media folder, because I want some pictures, swfs and so on on their personal pages, which other users can't access by simply typing in the URL of the media folder they want to access. How can I do that? The user himself doesnt need to access the folder, only the pages where he's the only one who can visit them, need to be able to access his/her media.

Thanks
