将图像导入tkinter

Question

Ok so I'm currently writing a simple image viewer and I have enough code to be able to view those images, but the only problem is to view the images you want. You have to put them in the same directory as the script and rename them. I want the user to be able to click something like file-open and then import those images. I'm currently using Tkinter as my Gui and PIL for displaying the images. here is my latest code:

from PIL import Image, ImageTk
from Tkinter import Tk, Label, BOTH
from ttk import Frame, Style
import os
import PIL
import Tkinter 

filename = "test.jpg"
filename2 = "test1.jpg"
filename3 = "test2.jpg"
filename4 = "test3.jpg"
basewidth = 300
img = Image.open(filename)
wpercent = (basewidth / float(img.size[0]))
hsize = int((float(img.size[1]) * float(wpercent)))
img = img.resize((basewidth, hsize), PIL.Image.ANTIALIAS)
img.save('resize.jpg')

basewidth = 300
img = Image.open(filename2)
wpercent = (basewidth / float(img.size[0]))
hsize = int((float(img.size[1]) * float(wpercent)))
img = img.resize((basewidth, hsize), PIL.Image.ANTIALIAS)
img.save('resize2.jpg')

basewidth = 300
img = Image.open(filename4)
wpercent = (basewidth / float(img.size[0]))
hsize = int((float(img.size[1]) * float(wpercent)))
img = img.resize((basewidth, hsize), PIL.Image.ANTIALIAS)
img.save('resize4.jpg')
class Example(Frame):



    def __init__(self, parent):
            Frame.__init__(self, parent)   

            self.parent = parent

            self.initUI()

    def initUI(self):

            self.parent.title("Picture")
            self.pack(fill=BOTH, expand=1)

            Style().configure("TFrame", background="")

            image1 = Image.open("resize.jpg")
            bardejov = ImageTk.PhotoImage(image1)
            label1 = Label(self, image=bardejov)
            label1.image = bardejov
            label1.place(x=5, y=5)

            image2 = Image.open("resize2.jpg")
            bardejov = ImageTk.PhotoImage(image2)
            label1 = Label(self, image=bardejov)
            label1.image = bardejov
            label1.place(x=5, y=250)

            image3 = Image.open("resize3.jpg")
            bardejov = ImageTk.PhotoImage(image3)
            label1 = Label(self, image=bardejov)
            label1.image = bardejov
            label1.place(x= 350, y=5)

            image3 = Image.open("resize4.jpg")
            bardejov = ImageTk.PhotoImage(image3)
            label1 = Label(self, image=bardejov)
            label1.image = bardejov
            label1.place(x= 350, y=250)

def main():

     root = Tk()
     root.geometry("660x488")
     app = Example(root)
     root.mainloop()  

if __name__ == '__main__':
     main()

Here you go - I do it for one image, you do it for all others similarly

import tkFileDialog
from Tkinter import *
from PIL import Image
import os

root= Tk()

def resizeIt():
    filename = tkFileDialog.askopenfilename()
    basewidth = 300
    img = Image.open(filename)
    wpercent = (basewidth / float(img.size[0]))
    hsize = int((float(img.size[1]) * float(wpercent)))
    img = img.resize((basewidth, hsize), Image.ANTIALIAS)
    img.save('resize.jpg')
    os.remove(filename) # deletes the original image after you have got the resized image


Button(text='add image', command=resizeIt).pack()

root.mainloop()

Edit after your question in comment

Yes you can delete a file using the os module. First you import os in the current namespace and then after you have saved the resized image, you add a line os.remove(filename) . I have done that in the above code.
