If you're talking about storing multiple frames in a single
(non-animated) image, Pete demonstrates this nicely in SolarWolf. The
code is quite readable. This code is found in gfx.py:

def animstrip(img, width=0):
    if not width:
        width = img.get_height()
    size = width, img.get_height()
    images = []
    origalpha = img.get_alpha()
    origckey = img.get_colorkey()
    img.set_colorkey(None)
    img.set_alpha(None)
    for x in range(0, img.get_width(), width):
        i = pygame.Surface(size)
        i.blit(img, (0, 0), ((x, 0), size))
        if origalpha:
            i.set_colorkey((0,0,0))
        elif origckey:
            i.set_colorkey(origckey)
        images.append(optimize(i))
    img.set_alpha(origalpha)
    img.set_colorkey(origckey)
    return images

 He was hungry, and had spotted himself as a nearby convenient object!
