PILでもこれは簡単です。空の画像を作成し、必要な任意の位置にある画像をpasteで貼り付けます。ここでは簡単な例です:

import Image 

#opens an image: 
im = Image.open("1_tree.jpg") 
#creates a new empty image, RGB mode, and size 400 by 400. 
new_im = Image.new('RGB', (400,400)) 

#Here I resize my opened image, so it is no bigger than 100,100 
im.thumbnail((100,100)) 
#Iterate through a 4 by 4 grid with 100 spacing, to place my image 
for i in xrange(0,500,100): 
    for j in xrange(0,500,100): 
     #I change brightness of the images, just to emphasise they are unique copies. 
     im=Image.eval(im,lambda x: x+(i+j)/30) 
     #paste the image at location i,j: 
     new_im.paste(im, (i,j)) 

new_im.show() 

enter image description here
