No. And that's because Tkinter's PhotoImage class doesn't understand
JPEG files. Fredrik Lundh says in his excellent An Introduction to
Tkinter at (wrapped for line length)

http://www.pythonware.com/library/tkinter/
  introduction/x6338-options.htm

regarding the PhotoImage class:

The file can contain GIF, PGM (grayscale), or PPM (truecolor)
data. Transparent regions in the GIF file are made transparent.  To
handle other file formats, use the corresponding class in the Python
Imaging Library.

And Fredrik's PIL is at

http://www.pythonware.com/downloads/index.htm#pil

and when you have it installed, you can do:

>>> from Tkinter import *
>>> import PIL.ImageTk
>>> r=Tk()
>>> i=PIL.ImageTk.PhotoImage(file="foo.jpg")
>>> c=Canvas(r)
>>> c.pack()
>>> c.create_image(0,0,image=i)
