Images aren’t converted or served with webp on google

Hello,

Hope you are well.

We are optimizing all the images with Litespeed cache to webp.

However, all the image aren’t converted to webp or aren’t properly configured to be served in webp.

You can see it on the website (linked shared).

And on the video:

When I deactivate the resize feature image option of the theme option and the webp version is shown. Screenshot: https://nimb.ws/pGaFbr

The issue is with images with lots of random character at the end which are generated by the theme:

/wp-content/uploads/thumbs_dir/DODONATUREL-Breathart-matelas-bebe-bio-et-ecologique-1xw4qbv6qwi0cmbzm1zk16m4p663o1jcmx3p0rhcov5o.jpg

And does give us a “bad score” on Google page speed because they are not WebP…

How can we make sure does image are served on webp with litespeed cache?

Not sure but it seems that it might be because litespeed cache doesn’t detect those groups of an image created by the theme, or we have to set a special attribute so that those images can be replaced by the webp version?

Here a screenshot https://nimb.ws/oYvfdQ of the groups of images processed by litespeed cache, so you can check if the groups containing those kinds of image /wp-content/uploads/thumbs_dir/DODONATUREL-Breathart-matelas-bebe-bio-et-ecologique-1xw4qbv6qwi0cmbzm1zk16m4p663o1jcmx3p0rhcov5o.jpg are on it.

Also, the configuration of the attribut on litespeed: https://nimb.ws/uU3gRJ

So, you can tell me if I need to add another one so that your resized images can be served in webp.

Hope you can help on this, thanks in advance.

Kind regards,

Marco
