[TYPO3] Make header image depend on language

True, so what would happen...it should revert to default.

I just tried it on a site and it goes back to the TYPO3 default language
which is 0 even though the url was &L=56

And because no 'valid' L was found the nav typolinks just drop the &L=56.

Thanks.
