Not all images are being smushed

Confused…how can it be that I SmushPro all my images and I end up with -3 improvement, the overall score has gone down? I have 5000 images.

    Hello Drinky,

    I hope you are doing well today! I apologize for the delay getting back to you.

    I could see that your all images are smushed. I also could see that your Hummingbird image optimization score is 96. Could you please recheck your site.

    Let me know if this will work for you. Have a great day!

    kind regards,

    Hello drinky,

    I checked your site and images are smushed. Performance report has two reports for image optimization.

    1. Losslessly compressing – This one's is telling that image can be optimized and that's what smushing does.

    2. Compressing and resizing – This shows that the images are resized via HTML and CSS

    The second one is what's shown in your results and that's because your theme is loading images larger than it's HTML holder, for example 800×447 thumbnails on home page but the actual HTML holder of that image is 330×186 so the image is resized with CSS to fit in that holder.

    Unfortunately this is not something Smush can deal with since the theme code is written in the way to call the larger image, and even though the image is compressed google doesn't like loading image larger than its holder, so this is something you need to check with the theme devs.

    If your theme allows you can check if you can load there a smaller images and change them.

    kind regards,
