title: Transparent background in a Tkinter window
body: <p>Is there a way to create a "Loading Screen" in Python 3.x using Tkinter? I mean like the loading screen for Adobe Photoshop, with transparency and so on.  I managed to get rid of the frame border already using:</p>
  
  <pre><code>root.overrideredirect(1)
  </code></pre>
  
  <p>But if I do this:</p>
  
  <pre><code>root.image = PhotoImage(file=pyloc+'\startup.gif')
  label = Label(image=root.image)
  label.pack()
  </code></pre>
  
  <p>the image displays fine, but with the grey window background instead of transparency.</p>
  
  <p>Is there a way of adding transparency to a window, but still displaying the image correctly?</p>
