 * I need to know how your image optimizer works because my images (images used 
   inside a post, product images, posts featured images, LD lesson, and topic featured
   images) are missing after we disabled JetPack.
   The image URL looks like this[https://i0.wp.com/genealogytv.org/wp-content/uploads/2022/09/Webite-Logos-Join-Info-Access-on-YT.jpg?resize=460%2C270&ssl=1](https://i0.wp.com/genealogytv.org/wp-content/uploads/2022/09/Webite-Logos-Join-Info-Access-on-YT.jpg?resize=460%2C270&ssl=1)
   Does that mean you are uploading my images to your servers and replacing the 
   URL with your CDN version?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fhow-does-image-optimizing-works%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hey [@hcmendez](https://wordpress.org/support/users/hcmendez/) – To clarify, 
   when you enable Jetpack’s Image CDN, your images are optimized and served from
   our servers to improve your site’s performance. However, we do not replace or
   overwrite the original image files on your site. The images remain stored in 
   your Media Library with their original URLs.
 * The URLs you’re seeing (e.g., `https://i0.wp.com/...`) are the CDN-hosted versions
   that Jetpack serves to site visitors for faster loading. If you disable Jetpack’s
   Image CDN, your site should revert to using the original image URLs hosted on
   your server automatically. Images should not disappear because we don’t remove
   or replace your original image files.
 * I visited your site and I see the images are loading on the site on the website
   URL. Could you please confirm if the issue is still there?
 * If your images are still missing after disabling the Image CDN, it may indicate
   an issue unrelated to Jetpack (e.g., a caching issue probably).
 * Could you please ensure that your Media Library is intact and images in Media
   Library are loading? Also, if you have any cache plugins installed, please clear
   the site cache to see if that helps in resolving the issue.

 * Hi there, [@hcmendez](https://wordpress.org/support/users/hcmendez/),
 * Do you have updates about that, do you still need help? We usually close inactive
   threads after one week of no movement, but we want to make sure we’re all set
   before marking it as solved. Thanks!
