thanks in advance

yes, works fine without imagify.
thought maybe you have a quick css.
try to get somebody on imagify.
thanks a lot.

Yes, thanks. They just got back to us. We changed settings for imagify from –
use <picture> tag
to
use rewrite rule
So all images on the page are jpg/png, but served threw rewrite as webp.
Thank you.

An for all with the same issue i will post the answer from imagify:
Imagify’s “Use <picture> tags” option (the default and likely what you’re currently using) swaps out your page’s tags for <picture> tags in order to display WebP images while also providing fallback support for users of older versions of Apple Safari browsers (they don’t support WebP images). If you’re having layout or display issues, this is most often the cause.

To resolve this, you can try switching to the “Use rewrite rules” option in your Imagify plugin settings page as long as you don’t use a CDN, Cloudflare, or certain cache services like Varnish (as these conflict and may cause image display issues, especially in Safari browsers).

It’s worth noting that when using the rewrite rules option, the HTML code of your pages will still show the JPG or PNG versions of images, but the rewrite rules work in the background to actually serve the WebP versions.

You can follow the Rewrite Rules section of this guide to check that WebP images are being served: https://imagify.io/documentation/how-to-check-if-webp-image-is-displayed-on-your-site/.

In case you can’t use the “Use rewrite rules” option, you could instead try installing the following helper plugin, as it’s possible it could help with this issue (works just by being installed and activated). It’s also possible that it won’t help, but it is worth a try:

https://github.com/wp-media/imagify-helpers/raw/master/webp/imagify-keep-attributes-on-img-tags/imagify-keep-attributes-on-img-tags.zip

If that doesn’t work, you can uninstall the above helper plugin, and instead try to use the following HTML class that can be added to specific images (the logo in your case) to prevent WebP display via <picture> tag replacement for those specific images (the optimized JPG/PNG versions will be displayed instead). If you can add this HTML class to your logo, then the images without any issues can still be displayed in WebP format.

If neither of these can work for you, then it will likely be best to disable WebP display in your Imagify plugin settings page for the time being (you can still keep creating the WebP versions for future use though.

That should resolve the layout/display issues with your logo and will still result in the Optimized JPG/PNG versions being displayed on your pages, so they should still be loading much faster than before they were optimized.
