How to fix AttributeError: 'Image' object has no attribute 'seek'. Did you mean: 'seed'?

Question

I am trying to create a pptx or powerpoint file using python-pptx and reading the image using python wand library but getting error like AttributeError: 'Image' object has no attribute 'seek'. Did you mean: 'seed'?

Note: All the files are in same folder starts with 'watermarked_'

from io import FileIO
import os
from wand.image import Image
from pptx.util import Inches 
from pptx import Presentation 

def create_slide()->FileIO:
    # Creating presentation object
    root = Presentation()
    for file in os.listdir():
        if file.startswith('watermarked_'):
            # Creating slide layout
            first_slide_layout = root.slide_layouts[1] 
            slide = root.slides.add_slide(first_slide_layout)
            shapes = slide.shapes
            
            #Adding title or heading to the slide
            title_shape = shapes.title
            title_shape.text = f" Created By python-pptx for Watermarking "
            
            #Adding sub-title with border to the slide
            body_shape = shapes.placeholders[1]
            tf = body_shape.text_frame
            tf.text = f"This is a watermarked image of {file}"
                
            with Image(filename = file) as watermarked_image:
                
                #Maintianing the aspect ratio of the image
                width, height = watermarked_image.size
                ratio = height/width
                new_width = width / 2
                new_height = int(new_width * ratio)
                watermarked_image.resize(int(new_width), new_height)
                
                # Add the watermarked image to the slide
                slide.shapes.add_picture(watermarked_image ,Inches(1), Inches(3))
                root.save("Output.pptx")

create_slide()

Any frequent help will be much appreciated

A wand.image.Image object is not a valid argument for Shapes.add_picture(). The first argument to that call needs to be the str path to an image file or a file-like object containing an image.

I suppose that means you'll need to save the modified image as a JPG or PNG or whatever and then provide the filename. You could also save it to a BytesIO object and pass that to .add_picture() as that would count as a file-like object and not require using the filesystem.
