Confused about two files

Not a biggie, but I’m confused as to why two image files are being served direct from my website and not the CDN. These files do exist on the CDN and I can find nothing in my Wordpress config that would prevent them being served from there.

Anyone any clues?

Are they hard-coded in the theme file? What plugin are you using to cause the content to be served from the CDN? Wordpress usually likes to serve from the same domain so it’s not so much a case of “would prevent them from being served there” as a case of “the plugin isn’t rewriting these two images for some reason”.

Thanks for the reply Patrick. After a lot of searching I did find the URL’s hard coded into a CSS file, managed to edit it & get the two files served from the CDN without breaking anything
