BuddyPress.org

Is there a Shortcut available to reference to the Template/Theme directory?

I tried something like this, but unfortunately there is no BP_TEMPLATE_URL available:

‘echo ‘root_domain . ‘”><img id=”admin-bar-logo” src=”‘ . apply_filters( ‘bp_admin_bar_logo_src’, BP_TEMPLATE_URL . ‘/images/admin_bar_logo.gif’ ) . ‘” alt=”‘ . apply_filters( ‘bp_admin_bar_logo_alt_text’, __( ‘BuddyPress’, ‘buddypress’ ) ) . ‘” />‘;

?>’

Does anyone knows the correct Tag for this? I also want to move the admin_bar_logo.gif into my theme directory.
