title: Python PIL Paste
body: <p>I want to paste a bunch of images together with PIL. For some reason, when I run the line <code>blank.paste(img,(i*128,j*128))</code> I get the following error: <code>ValueError: cannot determine region size; use 4-item box</code></p>
  
  <p>I tried messing with it and using a tuple with 4 elements like it said (ex. (128,128,128,128)) but it gives me this error: <code>SystemError: new style getargs format but argument is not a tuple</code></p>
  
  <p>Each image is 128x and has a naming style of "x_y.png" where x and y are from 0 to 39. My code is below.</p>
  
  <pre><code>from PIL import Image
  
  loc = 'top right/'
  blank = Image.new("RGB", (6000,6000), "white")
  
  for x in range(40):
      for y in reversed(range(40)):
          file = str(x)+'_'+str(y)+'.png'
          img = open(loc+file)
          blank.paste(img,(x*128,y*128))
  
  blank.save('top right.png')
  </code></pre>
  
  <p>How can I get this to work?</p>
