I have this .htaccess code that works to display most of my page. but for some reason it's not displaying the header image. the header is being called because the login and register links are being displayed.

RewriteRule ^face_off/([a-z0-9A-Z_-]+)/([a-z0-9A-Z_-]+)/$ battle.php?id=$1&title=$2 [L,QSA]

page with no header -http://www.youtubefaceoff.com/face_off/10/Gummy_bear_original_VS_Gummy_bear_remix

page with header - http://www.youtubefaceoff.com/

if you know what would be causing this problem please let me know. thnx.
