Hello,
Thank you for contacting Rank Math support today and bringing your concern to our attention.
Yes, it is advisable to redirect the attachment pages to their respective content as the page is not very useful for SEO unless you’ve dedicated photography or artwork or a graphic design website.
The images will still be indexed on the SERP even with the attachment pages being redirected since the images are already mentioned or attached to your post’s content.
You may refer to more about it here: https://rankmath.com/kb/should-you-redirect-attachments/
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
