Thank you for helping!
I reproduce your code in my nb file.
I did not know how to fix figures by ImagePad and ImageCrop.
I have a question about below code in taking the image.
Why is the image needed floor?
Does the image have a issue?
(*Let's slice off the left image.It will be our reference \
image.*)leftImage =
ImageTake[croppedImage,
All, {1, Floor[ImageDimensions[croppedImage][[1]]/2] - 1}]
