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.

We have separated your concern into a new ticket so we can assist you accordingly.

Please be advised that Google decides solely when it’s a matter of indexing a post/image on SERPs. Here, what you can do is improve the quality of your content/images.
