Hi @evasonder,
Thanks for your feedback, if Google Translate is correct you are experiencing some issues with reported thumbanil sizes.
Smush will check the size of the image loaded and the holder around that image, if the image is larger than the holder itself it will show in the report as this is one of the things Google will report in its page speeed tests as well so it’s a suggestion with which you can improve your site loading speed further.
Since you are using WooCommerce you should be able to address this by adjusting the image sizes it uses.
You can do this by going to Appearance > Customize > WooCommerce > Product Images and adjust the size there to fit your image holders.
Note that the notification you are mentioning is not visible to site visitors so they won’t be bothered by it, but if you wish to turn it off for yourself as well you can go to Smush > Tools and disable “Image Resize Detection” option.
Hope this helps ??
Cheers,
