  It doesn't matter if the server is using a buffered stream, you'll
get the bytes on the client anyway. Maybe something like this helps
(haven't tried it):

data = nil
left = nombre_bytes
while left > 0
  # 8192 is an arbitrary buffer size
  buf = socket.read( left > 8192 ? 8192 : left )
  # eof reached
  break unless buf

  left -= buf.size
  data += buf
end

@imageData = data


Why are you using a while to read return code, filename and size?
Three socket.readline should be enough.
