Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Are you using any page builder plugin to add those images?
If so, could you please tell us which one?
Looking forward to helping you.
Hi!
I post a NEW POST and add photos normally. Please check this URL: https://haiphongtours.com/vi/diem-tham-quan-du-lich-o-hai-phong/
I add featured image, add media and upload pics… There’s no relative to any page builder.
THank you Anas
PS: I am using Core 5.6, Flatsome 3.13.1., WP Rocket 3.8.3
Thank you again
Hello,
Rank math usually allows the option to include images in their attached sitemap URLs.
You can enable the option to include your images in sitemap in
Rank math > Sitemap Settings > General:

After saving the sitemap settings, please clear the cache.
I hope this helps. Looking forward to helping you.
Hi!
Thank you so much for pretty quick SP.
I have no idea why when I Enable “Include Images from the ACF Fields.”
It worked.
All set now. Thank you Anas for amazing SP.
