PageSpeed Issue: bad LCP metric due to mobile theme feature images loading slow

Posted in: Newspaper

Dear Support Team

I am having the same issue with the TownTalk Child theme. LCP check is failing for mobile view in Google Page Speed tests. LCP for the mobile view of posts is about 5 seconds.

I am using WP Rocket Premium with all optimizations turned on.

Obviously, this is mainly related to the thumb image on top of the posts. This image is loaded in full size and then resized to the mobile width.

For some reason, I did not have this issue when installing the theme first time. Could it have turned up with the latest version updates?

There must be a better way to include this image. I assume, that all your child themes have this same issue.

If there is no way of optimizing this part from a developers point, would it be possible to do a custom workaround: removing this feature image from the mobile theme for posts and pages?

Looking forward to a feedback on this.

Best regards
Joachim

Hello Joachim!

Do you mean these thumbs?: https://forum.tagdiv.com/thumbs-on-modules-and-blocks/
If you deactivate a dimension from there, next time when you will upload an image, it will not be resized to that dimension.
After changing the thumbnail sizes you need to regenerate your thumbnails using a plugin. Check this: https://forum.tagdiv.com/using-the-theme-with-existing-content/
NOTE: If the thumb specific for that block is not enabled, then the image won’t be displayed.
NOTE: The Mobile theme layout is not customizable as the responsive version or mobile pages. Please see https://forum.tagdiv.com/the-mobile-theme/ and https://forum.tagdiv.com/mobile-theme-introduction/ for more information.

Please provide an example of the issue you have now, and it wasn’t when you installed the theme, so we can check if there is a bug or not. You have the option to hide the featured images from Flex Block, for example.

Thank you!
