I use PIL (Python Imaging Library) module which is more flexible with graphics usage in python and let you use formats different from say gif.
So I advise you first to install PIL from here http://www.pythonware.com/products/pil/
Then a very simple example which focus only on the load image and canvas part:

 python Syntax (Toggle Plain Text) 
#here you import the module
from PIL import Image, ImageTk
#here you load the image you are going to use
Logo_IMG = Image.open("C:\Python25\..........\Logo.png")
#here you use Photoimage to assign the image to ImageTk
Logo_TK = ImageTk.PhotoImage(Logo_IMG)
#here you create a simple canvas widget -I assume you have already a frame to put it
Canv_logo = Canvas(your_canvas_frame, width=50, height=50, bg="white", bd=0)
#here you show the image in the canvas
Canv_logo.create_image(36, 36, image=Logo_TK)
Canv_logo.grid()
#here you reference at the image again -without this you won't see the image-
Canv_logo.image = Logo_TK
#here you import the module
from PIL import Image, ImageTk
#here you load the image you are going to use
Logo_IMG = Image.open("C:\Python25\..........\Logo.png")
#here you use Photoimage to assign the image to ImageTk
Logo_TK = ImageTk.PhotoImage(Logo_IMG)
#here you create a simple canvas widget -I assume you have already a frame to put it
Canv_logo = Canvas(your_canvas_frame, width=50, height=50, bg="white", bd=0)
#here you show the image in the canvas
Canv_logo.create_image(36, 36, image=Logo_TK)
Canv_logo.grid()
#here you reference at the image again -without this you won't see the image-
Canv_logo.image = Logo_TK

I hope this can be of help.

By the way I've noticed that in windows the image is bordered by default Tk gray. Even if I try to set frame/widget bg and bd to white the gray border stays there and grey anyway... Any suggestion for solving this issue?
