Make image from uint8 RGB pixel data

I am trying to make a library related to RGB pixel data, but cannot seem to save the image data correctly.

That is my output image. This is my code:

pixelmanager.py

from PIL import Image
import numpy as np

class MakeImgFromPixelRGB:
    def createIMG(PixelArray: list, ImgName: str, SaveImgAsFile: bool):
        # Convert the pixels into an array using numpy
        array = np.array(PixelArray, dtype=np.uint8)
        if SaveImgAsFile == True:
            new_image = Image.fromarray(array)
            new_image.save(ImgName)
class getPixelsFromIMG:
    def __init__(self, ImagePath):
        im = Image.open(ImagePath, 'r')
        width, height = im.size
        pixel_values = list(im.getdata())
        self.output = pixel_values

test.py

import pixelmanager

a = pixelmanager.getPixelsFromIMG(ImagePath="download.jpg")

pixelmanager.MakeImgFromPixelRGB.createIMG(a.output, "output.png", True)

with open("output.txt", "w") as f:
    for s in a.output:
        f.write(str(s) + "," + "\n")

I have tried to de-scale the image in paint.net and also tried to mess with the uint size.

Mark Setchell was ALMOST correct. His code did help me get an image, but it was repeated 4 times in one.

Mark's line of code had a switchup (with h as height and w as width):

array = np.array(PixelArray, dtype=np.uint8).reshape(h,w,3)

This is my line of code:

array = np.array(PixelArray, dtype=np.uint8).reshape(w, h, 3)
