size check added
Images with same sizes added. otherwise it gives out warning and returns None.
Also, added comparison for numbers
I think for tuples, it's taking individual indices, which is undesirable. I have ask Kat about it
Should it give out binary image, or color image?

comparison fixed
I'm not going to make it complicated. Images will not be binary images. Each color of each pixel will have its effect
