Hi, change def image like this

def image(self, data, num):
    image = {}
    height = data["imageHeight"]
    width = data["imageWidth"]
    image["height"] = height
    image["width"] = width
    image["id"] = num
    image["file_name"] = data["imagePath"].split("/")[-1]

    self.height = height
    self.width = width

    return image
