Moved WordPress Domain, now having Permalink Issues

Hi
I have recently moved a wordpress site from one domain to another, but am having a few problems.

1) My image links did not update
2) The image on Really Simple Captcha no longer works
3) My custom 404 page is no longer styled.

I tried to update the permalinks in the database using the following queries:

UPDATE wp_options SET option_value = replace(option_value, 'https://www.oldurl', 'https://www.newurl') WHERE option_name = 'home' OR option_name = 'siteurl';

UPDATE wp_posts SET guid = replace(guid, 'https://www.oldurl','https://www.newurl');

UPDATE wp_posts SET post_content = replace(post_content, 'https://www.oldurl', 'https://www.newurl');

UPDATE wp_postmeta SET meta_value = replace(meta_value,'https://www.oldurl','https://www.newurl');

but it does not seem to have worked. I have also tried the Plugin Velvet Blues but this didn’t work either.

Can anyone offer any suggestions?
Thanks
