Replacing CDN Image URLs with Original URLs in Sitemap

Dear Rank Math Support Team,

I hope this message finds you well.

I am currently facing an issue where my Rank Math-generated sitemap includes Cloudflare CDN URLs for images instead of the original image URLs. I believe that having the original image URLs in the sitemap is a better practice for image SEO, as it improves the chances of my images being indexed and appearing in Google Search.

To address this, I attempted to add the following code to my theme’s rank-math.php file to replace the CDN URLs with the original URLs in the sitemap:

Unfortunately, this code does not seem to resolve the issue, as the sitemap still includes the CDN URLs.

Could you please advise on how to properly implement this replacement? If there’s a better approach or specific guidance for handling this within Rank Math, I’d greatly appreciate your support.

Thank you for your time and assistance.

Best regards,
Thuy
