Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
For initial troubleshooting, please make sure that your sitemap is not cached. Please follow these steps:
1. Ensure you’re using the latest version of your plugins/theme including Rank Math
2. Flush the Sitemap cache by following this video screencast:

3. Exclude the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server:

I hope that helps.
Thank you.
Followed the steps but still no images
Hello,
Please make sure that you have enabled “Images in Sitemap” and “Include Featured Images” under Rank Math > Sitemap Settings > General.

We hope that helps. We are here if you need us again.
