python button does not work when image is added
Question: When I try to add and image to the button, the program will run, but the
button will be blank and you cannot click on it. If I change
`image=Tkinter.PhotoImage(file="C:/TeDOC/OpenFolder.gif")` to `text='Open
Directory` it works fine and you are able to click the button. I have no idea
why when I change it to an img, it does not work. Any help will be
appreciated.

Here is my code:

    
    
    import Tkinter, Tkconstants, tkFileDialog
    
    class TkFileDialogExample(Tkinter.Frame):
    
    def __init__(self, root):
    
    Tkinter.Frame.__init__(self, root)
    
    # options for buttons
    button_opt = {'fill': Tkconstants.BOTH, 'padx': 5, 'pady': 5}
    
    # define buttons
    Tkinter.Button(self, image=Tkinter.PhotoImage(file="C:/TeDOC/OpenFolder.gif"), command=self.askdirectory).pack(**button_opt)
    
    # defining options for opening a directory
    self.dir_opt = options = {}
    options['initialdir'] = 'C:\\'
    options['mustexist'] = False
    options['parent'] = root
    options['title'] = 'This is a title'
    
    
    def askdirectory(self):
    #Returns a selected directoryname.
    return tkFileDialog.askdirectory(**self.dir_opt)
    
    if __name__=='__main__':
      root = Tkinter.Tk()
      TkFileDialogExample(root).pack()
      root.mainloop()
    


Answer: First you have to define your image, using the self.image. So try:

    
    
    self.image = Tkinter.PhotoImage(file="C:/TeDOC/OpenFolder.gif")
    

Then under your button, put:

    
    
    Tkinter.Button(self, image=self.image, command=self.askdirectory).pack(**button_opt)
