Newbie Tkinter Problem

[Colleen & Brian Smith]

In the script below, when I hard-code the file name, the button works fine.
However, when I use the askopenfilename dialog, something is preventing the
button from working normally. If somebody could
point out where I'm going wrong, I'd sure appreciate it.

--------------------------------------
from Tkinter import *
import Image, ImageTk
from viewer import UI
from tkFileDialog import *

class Application(Frame):

    def createWidgets(self):
  self.QUIT = Button(self)
  self.QUIT["text"] = "QUIT"
  self.QUIT["fg"]   = "red"
  self.QUIT["command"] =  self.quit
  self.QUIT.pack(side=LEFT)

    def LoadPic(self):
  self.picname=askopenfilename(filetypes=[("JPEG", "*.jpg")])
  self.pic = Image.open(self.picname)
  self.pic.thumbnail((128, 128))
  self.display = UI(self,self.pic)
  self.display.pack(side=RIGHT)

    def __init__(self, master=None):
  Frame.__init__(self, master)
  self.pack()
  self.createWidgets()
  self.LoadPic()
  self.pack()

app = Application()
app.mainloop()
