title: Can't paste resized image in Pillow
body: <p>I have a problem with pasting a resized image in Pillow module. I want to adjust a watermark to all images of any size with 1/3 width of the image width and maintain the ratio aspect 65:10, after pasting a resized image I get this error:</p>
  
  <pre><code>(480, 360)
  (160, 25)
  Traceback (most recent call last):
    File "C:/Users/Przemek/PycharmProjects/cwiczenia/venv/project watermark.py", line 15, in &lt;module&gt;
      image.paste(watermarkResized, (0,0))
    File "C:\Users\Przemek\PycharmProjects\cwiczenia\venv\lib\site-packages\PIL\Image.py", line 1504, in paste
      raise ValueError("cannot determine region size; use 4-item box")
  ValueError: cannot determine region size; use 4-item box
  </code></pre>
  
  <p>Here is the code:</p>
  
  <pre><code>import os
  from PIL import Image
  directory = "PATH TO THE DIRECTORY"
  watermark = Image.open("PATH TO THE WATERMARK")
  
  for filename in os.listdir(directory):
      image = Image.open("PATH TO THE DIRECTORY"+filename)
      imageWidth, imageHeight = (image.size)
      watermarkResized = watermark.resize(((int(round((imageWidth/3),0)), int(round(((imageWidth/3) /6.5),0))))).copy
  
      print(image.size)
      print(watermarkResized.size)
  
  
      image.paste(watermarkResized, (0,0))
      image.save("PATH TO THE DIRECTORY"+filename+".png")
  </code></pre>
