Pictures keep disappearing

Hi All

Our pictures keep disappearing (including our logo). Please advise on what is going wrong.

The pics and logo were all uploaded in the form of png/jpg.

Kind Regards

Look at the url’s for the images, these are webp. Those that do appear are png.

Thank you. Why would it keep changing the format? We 100% uploaded png format

It looks like mod_pagespeed rewrites the image URL to an optimized format
