a hidden bug about image_size

[ShuaiLYU]

Dear Runinho,

I found that you use " h = img.size[0] w = img.size[1]" in the cutpaste.py. I think it should be " w = img.size[0]
h = img.size[1]" here. the reason the bug haven't been triggered is that the images used in this dataet have same width and height.

Amending the bug is appreciated.

Thanks and Best Regards.
