GALLERY imagefield + imagecache subfolder

Hi, i would like to build a image gallery with:
+ imagefield;
+ imagecache;
+ cck;
+ taxonomy;
+ views;

(i follow the tutorial in doc page..), but now i would like to store images in different way, for example if user1 go to paris:

/IMAGES/2008/11/04/PARIS/user1

if there is another user2 who goes to paris in the same date, path will be:

/IMAGES/2008/11/04/PARIS/user2

Date, user who upload pictures, and location change dinamically...

Also, i would like to rename photos when uploaded according to node for example...

How do that? I read around posts in forum, and I think i must use token for doing that...(in a past topic, i read i will use filefield_paths, but i try this, and i not know how i setup the path... :S) Any suggestions will be apreciated! tx @ all...
