In Leopard the Top Menu Bar is fairly transparent and will overlay on top of the background image. For those who want to disable it the following command will do so:
write /System/Library/LaunchDaemons/com.apple.WindowServer 'EnvironmentVariables' -dict 'CI_NO_BACKGROUND_IMAGE' 1
If you later start to miss this menu bar then you can undo this change by using the following command:
defaults write /System/Library/LaunchDaemons/com.apple.WindowServer 'EnvironmentVariables' -dict 'CI_NO_BACKGROUND_IMAGE' 0
