Thanks for you answer Markus,

this is what I suspect, but I don't have any idea how I can check it.  
I mean, how can I see where the decompressed image is put? I tried  
giving a look at lib/inflate.c to check how gunzip() works, but I'm  
not able to figure out where inflated data goes....

Bye,

Ottavio.
