You should be able to this with beautifulsoup4 and PIL. I.e. grab all img tags with BS4, get the dimensions with PIL and then add a style attribute with BS4.

The following edit plugin code, which requires Sigil 0.9 (and higher) and the bundled interpreter, should work.

Spoiler:

#!/usr/bin/env python
# -*- coding: utf-8 -*- 
from sigil_bs4 import BeautifulSoup
from PIL import Image
import os

def run(bk):

    for (html_id, linear) in bk.getspine():
        mime = bk.id_to_mime(html_id)
        
        if mime == 'application/xhtml+xml':
            html = bk.readfile(html_id)
            soup = BeautifulSoup(html)
            orig_soup = str(soup)
            images = soup.find_all('img')

            for image in images:
                image_path = os.path.join(bk._w.ebook_root, 'OEBPS', 'Images', os.path.basename(image['src']))
                img = Image.open(image_path)
                width, height = img.size
                image['style'] = 'max-width: ' + str(width) + 'px'
                
            if str(soup) != orig_soup:
                bk.writefile(html_id, str(soup.prettyprint_xhtml(indent_level=0, eventual_encoding="utf-8", formatter="minimal", indent_chars="  ")))
                print(bk.id_to_href(html_id) + ' updated')
    
    return 0

def main():
    print ('I reached main when I should not have\n')
    return -1

if __name__ == "__main__":
    sys.exit(main())
