very dirty indeed ;-)

I really enhanced the Resource Management API a lot for Flow 2.1 - but 
it's not finished yet. There'll be an API method 
$resourceManager->getPrivateStorageUriByResource$resource) which will 
return exactly what you'll need:

$metaArr = 
exif_read_data($resourceManager->getPrivateStorageUriByResource($image->getResource()), 
0, true, false);

I hope to finish this part during the next two weeks or so. Does it make 
sense for you to wait until then?
