title: Tkinter canvas create image multiple times
body: <p>I use this function in my code to create an image on a canvas:</p>
  
  <pre><code>def _create_image(self, coord):
      (x,y) = coord 
      self.one = ImageTk.PhotoImage(Image.open("test.jpg"))
      root.one = self.one
      self.canvas.create_image(x-25, y-25, image=self.one, anchor='nw', tags="image")
  </code></pre>
  
  <p>My problem is that everytime i call this function the old image is deleted and a new one is created.</p>
  
  <p>How do i prevent the old image from being deleted? I want to create the image multiple times on my canvas.</p>
