Thank you Pete, I've found your ideas very interesting, in these days I've 
found also another way that use surfarray module(thanks to your tutorial :)
I've created a new file image 75x75(the same of the frames) and totally
trasparent, called "dummy", every frame I "clean" the old image with this
dummy and then I blit the new frame on it:

def __init__(self, filename, dummyfile):
  #load default image
  self.imagedef = pygame.image.load(filename).convert()
  #load dummy trasparent image
  self.dummy = pygame.image.load(dummyfile).convert()
  self.image = self.dummy
  #create an array of dummy 
  self.dummyarray = pygame.surfarray.array2d(self.dummy)

def update(self, x, y):
  #clean the old image with dummy
  pygame.surfarray.blit_array(self.image, self.dummyarray)
  #blit the new frame on image
  self.image.blit(self.imagedef, (0, 0), (x, y, 75, 75))

What do you think of this way?

thank you
