body: <p>I am trying to create a program which takes 128 images of a balloon which their size is increasing in a fixed change, and paste each on different copy of a fixed image with a certain size, the image are bellow and also the code, the code that i have made until now is pasting them on the upper left of the image and i wand every picture to be pasted on the middle of the lower border of the copy, so the problem over all is with the area var creation: 
  <a href="https://i.stack.imgur.com/K2VkZ.jpg" rel="nofollow noreferrer">the background</a>
  <a href="https://i.stack.imgur.com/RlLFS.jpg" rel="nofollow noreferrer">the balloon picture</a></p>
  
  <pre class="lang-py prettyprint-override"><code>from PIL import Image
  
  i = 0
  
  while(i &lt; 128):
      balloon = Image.open("NEAREST" + str(i) + ".jpg")
      canvas = Image.open("blank.jpg")
  
      area = (0 ,0,298+i,298+i)
      canvas.paste(balloon, area)
      canvas.save("PASTE"+str(i)+".jpg")
      i = i + 1
  </code></pre>
