Hi keemo,
If I understand the question correctly, you could just put something like "include("search.php?search_user=artist_name"); at the bottom of the member_profile page. Obviously, you'd need to replace artist_name with the var that holds the member name, and you might want to do a bit of editing in search php (copy it to search2.php or something first, so you the original search functions don't get screwed up), and delete the bits of the template that show the header, footer, sidebar, etc as they will already have been displayed by members.php
Not sure if that's what your after, but I hope it helps.
(Sorry it's not more specific, but I don't have access to my 4images atm, so I can't check any of the above).
Thanks,
Alan.
