Google finds most images through pages. The sitemap is a hint. After a WebP migration, regenerate it from live markup, do not hand-edit 10,000 rows.
Why it matters
- Ecommerce plugins generate stale image sitemaps.
- Converted files 404 if the sitemap is stale.
- OG JPEGs do not belong as page images in the sitemap.
How to do it
- Convert and update pages first.
- Regenerate the sitemap from the CMS.
- Spot-check 10
