Image URLs Returning 404 in Sitemaps: When Media References Decay Faster Than Pages
A page can stay healthy while its image references rot. When sitemap image URLs start returning 404, the media layer no longer matches the page the sitemap is trying to describe.
Why image 404s matter
Sitemap image extensions are supposed to reinforce real crawlable media. If the image URL is gone, replaced, or blocked, the sitemap carries stale media metadata.
How to audit the problem
Check whether image URLs still resolve, whether the page still uses them, and whether CMS or CDN workflows are retiring media faster than sitemap exports get refreshed.
