[TYPO3-english] usage of spriteManager in frontend

[Domi]

Hello,

I try to render a language menu with the TYPO3 backend flags. But here I 
stuck:
Is this possible? I tried
$spriteManager = t3lib_div::makeInstance('t3lib_SpriteManager', TRUE);
$spriteManager->loadCacheFile();

But its wasn't possible for getting any pictures out of it...

Thanks for any hint

Cheers
Dominic
