# Construct the album manager

# Let's get the baseUrl of the first item

# Let's format the baseUrl with parameters
# and prepare it for display within the Canvas

# Let's open the image from the URL thus created
image_bytes = urlopen(image_url).read()

# Boilerplate for a Tk window with a canvas
root = Tk()
# giving some border to the image
canvas = Canvas(root, width=320, height=320, bg='white')
canvas.pack(side='top', fill='both', expand='yes')

# We create a PIL Image with our raw image
img = Image.open(io.BytesIO(image_bytes))

# Now we prapare the image to be displayed,
# then we display it to the Tk window
photo = ImageTk.PhotoImage(img)
canvas.create_image(10, 10, image=photo, anchor='nw')

# In a script it needs to be finalized with the main loop
