# Usage:
#   python make_git.py <input_dir_name> <output_filename>

### Parameter
# Maximum number of images to be used (because a large number of images will result in an error)
IMAGE_COUNT_LIMIT = 200

# This is the display time for a single image. Lower the number, the smoother (finer) the GIF will be displayed.
