Rankmath has no review and image section in schema functionalties.

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention.

Please note that Rank Math doesn’t have any control over how images in the SERP results are displayed and search engines display them as per their will and it mostly depends on the keyword search term and the website authority.

You may try to add relevant ALT text to the featured image or image you wanted to show, and chances are search engines will refer to it.

Here’s a guide you can follow as well:

Looking forward to helping you.
