this is code to update exif

from PIL import Image
from PIL.ExifTags import TAGS, TAGS_V2

def update_exif_dimensions(image_path):
    # Open the image
    img = Image.open(image_path)
    
    # Get EXIF data
    exif_data = img._getexif()
    
    # Convert it to a dictionary for easier access
    exif_dict = {TAGS.get(k, k): v for k, v in exif_data.items()}
    
    # Update ExifImageWidth and ExifImageHeight with actual dimensions
    exif_dict['ExifImageWidth'] = img.width
    exif_dict['ExifImageHeight'] = img.height
    
    # Update the EXIF data in the image
    img._getexif().update(exif_dict)
    
    # Save the image with updated EXIF data
    img.save(image_path)

# Update for a specific image
image_path = "path/to/your/image.jpg"  # Replace with the actual path to your image
