how to put an image onto a sprite pygame

I am creating a game like pacman in pygame using python. I want to assign a image of a jewel to the jewel class. In the maze 'J' Represents the jewel. So just to make it clear how would i assign an image to the Jewel Class so that all the J's in the maze map are that image?

The class for the jewel is 

class Jewel(object):
    """Class to hold Jewel sprite properties"""

    def __init__(self, pos):
        jewels.append(self)
        self.rect = pygame.Rect(pos[0], pos[1], 16, 16)

The class for the wall and maze is 

class Wall(object):
    """Class to hold Wall sprite properties"""

    def __init__(self, pos):
        walls.append(self)
        self.rect = pygame.Rect(pos[0], pos[1], 16, 16)

walls = [] #List to contain walls
jewels = []#List to contain Jewels

#!-----------------------Maze Layout----------------------!

#Table used to create the level, where W = wall
level = [
"WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW",
"W       J               W          JJJ           W",
"W                       W     W                  W",
"W    WWWW   WWWWW   WWWWW     W      WWWWWWWWWW  W",

Just add the image as an attribute for your objects - for example, you can load them at the __init__ method like:

def __init__(self, pos):
    walls.append(self)
    self.rect = pygame.Rect(pos[0], pos[1], 16, 16)
    self.image = pygame.image.load("/path/to/image_file.png")

and then, on your game loop, instead of drawing a rect, call the blit method of the "screen" (which is a pygame.Surface object) passing the image:

for jewel in jewels:
    screen.blit(jewel.image, jewel.rect)

Later on when you have got a little more structure on the game, you should put your game objects in specialized sprite groups which can then make use of the .image and .rect attributes of the sprites to blit them to screen when the group draw method is called. (check the docs on http://www.pygame.org/docs/ref/sprite.html), instead of calling blit directly.
