Here is a script that does what you need:

#!/usr/bin/env python

"""
Get information about images in a folder.
"""

from os import listdir
from os.path import isfile, join

from PIL import Image


def print_data(data):
    """
    Parameters
    ----------
    data : dict
    """
    for k, v in data.items():
        print("%s:\t%s" % (k, v))
    print("Min width: %i" % data['min_width'])
    print("Max width: %i" % data['max_width'])
    print("Min height: %i" % data['min_height'])
    print("Max height: %i" % data['max_height'])


def main(path):
    """
    Parameters
    ----------
    path : str
        Path where to look for image files.
    """
    onlyfiles = [f for f in listdir(path) if isfile(join(path, f))]

    # Filter files by extension
    onlyfiles = [f for f in onlyfiles if f.endswith('.jpg')]

    data = {}
    data['images_count'] = len(onlyfiles)
    data['min_width'] = 10**100  # No image will be bigger than that
    data['max_width'] = 0
    data['min_height'] = 10**100  # No image will be bigger than that
    data['max_height'] = 0

    for filename in onlyfiles:
        im = Image.open(filename)
        width, height = im.size
        data['min_width'] = min(width, data['min_width'])
        data['max_width'] = max(width, data['max_width'])
        data['min_height'] = min(height, data['min_height'])
        data['max_height'] = max(height, data['max_height'])

    print_data(data)
