Pil Raw Image Viewer-- How to get image mode

[Andrew]

Hello Ive been messing around with a simple raw image viewer using Pil 
and Tkinter

However I am running into problems displaying the images they appear to 
be not correct I believe it is cause of the modes for the different 
files but I am unsure

If someone could examine my code and assist in helping me solve my 
problem(s)

It would be greatly appreciated

from Tkinter import *
import Image, ImageTk
import os
import tkFileDialog
size = 1024, 768

def getfiles():
     try:
         entry.delete(0, END)
         global fileopen
         fileopen = tkFileDialog.askdirectory()
         entry.insert(END, fileopen)
     finally:
         listb.delete(0, END)
         filenames = {'': []}
         getfileext = fileentry.get()
         path = entry.get()
         for root, dirs, files in os.walk(path):
             for name in files:
                 lname = name.lower()# if on windows
                 global names
                 for ext, names in filenames.iteritems():
                     if lname.endswith(getfileext):
                         names.append(os.path.join(root, name))
                         listb.insert(END, name)
                         break


def select(event):
     selection = listb.curselection()
     global selectit
     selectit = names[int(selection[0])]
     global im
     image_file = open(selectit, 'rb')
     data = image_file.read()
     im = Image.fromstring("RGB", (size), data, "raw")
     im.thumbnail((700, 700))
     image = ImageTk.PhotoImage(im)
     label["image"]=image
     label.image = image

root = Tk()
root.title("Engrooved Image Viewer")
root.wm_resizable(0, 0)
root.wm_iconbitmap("shinobi.ico")





frame = Frame(root)

im = Image.open("startimage.jpg")
image = ImageTk.PhotoImage(im)
##canvas = Canvas(frame, width=400, height=400)
##canvas.create_image(0, 0, image=image)
##canvas.grid(row=0, column=0, sticky=N+S+W+E)
label = Label(frame, image=image)
label.image = image
label.grid(row=0, column=0, sticky=N+S+W+E)

scrollbar2 = Scrollbar(frame)
scrollbar2.grid(row=0, column=2, rowspan=1, columnspan=1, stick=N+S)

listb = Listbox(frame, selectmode=SINGLE)
listb.grid(row=0, column=1, columnspan=1, sticky=N+S+W+E)
listb.bind('<ButtonRelease-1>', select)
scrollbar2.config(command=listb.yview)
listb.config(yscrollcommand=scrollbar2.set)
frame.grid(sticky=N+S+W+E)

frame3 = Frame(root)

entry = Entry(frame3)
entry.grid(row=1, column=1, stick=W+E, columnspan=1)
label2 = Label(frame3, text="EXT").grid(row=1, column=2)
fileentry = Entry(frame3)
fileentry.grid(row=1, column=3, columnspan=1, sticky=W+E)
button = Button(frame3, text="Open and List Directory", command=getfiles)
button.grid(row=1, column=4)
frame3.grid(sticky=W+E)


root.mainloop()
