need help please !!

I have installed the test site here:- http://www.socialmunch.com/D7-New-Setup/index.php

I have tried to migrate contents and profiles etc........  and use database back up  but for some reason its not showing things right (pics, sound, vids etc)

can you tell me why please ??? 

Did you also copy the related media over (e.g., avatars, photos, videos, etc.)? Also make sure to clear your /cache/ (except for the .htaccess file) and /cache_public/ directories afterwards.

how do I cope all media over please ???
