if the above code is in a loop, and there is no figure clearing in the loop, then rotated_images[i] = [] gc.collect(2) will have no effect since matplotlib will still have references to the array (and generally, you never need to call gc.collect by the way). What isn't clear to me in this is how you handle the offsetting and combining of images. Normally imshow will just display one image right over the other. Can you just insert the appropriate subsampled image into one output image, and then display that. After the insertion, you can delete the input image inside the loop.
