[Smush Pro] Smush CDN Scaled Images

When I run a GTMetrix report on spencercoffman.com everything looks good except serving scaled images. All of my images are coming from the Smush CDN. Is there a way to have SmushPro automatically scale the images it serves on a page? If not, is there another way I can boost this score without having to manually resize all of my images?

    Hi Spencer Coffman

    Hope you are doing good today.

    I checked the site source with Smush CDN enabled and disabled and from what I see theme core already handles images to be resize do different size of resolutions.

    If you inspect homepage source (CDN disabled), you should notice that the image displayed on the page seems to be fitting its container as expected (GTMetrix point only issue for each image about Losslessly compressing 3% which is very low, also GTMetrix score is then B 81%). So this confirm the theme is using srcset which means that there are multiple sized images “suggested” to browser at the same time and the browser decides which one to choose.

    If you enable Smush CDN it possibly conflict with this srcset attribute and at the end we get different page source with different sizes of those images. That is why GTMetrix point those ones.
    Also in this case GTMetrix score is very low -> C 34%.

    At the moment CDN is disabled on your site by me to get this score on at 81%, which is better.

    Please let me know if you have any other questions.

    Kind Regards,
    Kris
