I try to update profiles picturs with perl twitter api

my $result = $nt->update_profile_image('tux.png');

but I get
HTTP/1.1 403 Forbidden There was a problem with your picture. Probably too big.

I tried with several images and the same result
PD: I also tried with a tiny image (<1kb) and the same. Maybe I am sending bad the parameters?
