maybe what confused you were some of the more "advanced" suggestions
about using the Python Imaging Library (PIL) or installing a second
Python version or discussing the handling of namespaces.
In fact, as far as I see, there is not too much difference in the
Tkinter usage between Python2.7 and Python3, so for the most part the
old Python2-based Tkinter tutorials should still serve you well. The most
evident difference is that since Python3 the tkinter module spells in
lower case.
Coming back to the problem from your original post:

This line seems in fact to be taken from some tutorial describing the
usage of PIL. In plain Tkinter the simplest program displaying an image
might look like (Python3 version):
from tkinter import *
root = Tk()
img = PhotoImage(file='imagepath.gif')
l = Label(root, image=img)
l.pack()
root.mainloop()
The only difference to the "Python2-version" is the lower-case "Tkinter"
in the first line.
You see that in Tkinter you usually do not have to use the Image class at
all (although it exists) but create the image directly with the PhotoImage
class.
One (more or less serious) restriction of Tkinter's standard PhotoImage
class is however that you can only use GIF images, other formats like
JPEG or PNG are not supported yet. So unfortunately you will either have
to use an external tool to convert your jpegs into gif first or install a
third-party extension like PIL or TkImg* (the latter is easier to use if
you only need support for more file formats, because no commands are
changed or added, but just support for a lot of image file formats is
added silently in the background; I am not sure however if there is a
precompiled binary for windows systems is easily available) if you really
need these formats.
Did this help any?
Best regards
