 * Hi, i’m trying to use the new “add_theme_support(‘post-thumbnails’);” by adding
   it at the top of my functions.php file (after the <?php) but nothing appears 
   in the “modify post” page … i tried everything I found on the net but still unable
   to get the little thumbnail window on the right panel.

 * Well, it seems that in the 3.0, thumbnails have been replaced by featured image,
   but I can’t find any help on how to use it … Its weird that wordpress changes
   some functions like that without any clue to help us using it…
