Gallery image size : gtmetrix not happy

    Hi,
    i setup the gallery to be full width 2 rows of 5 images each they display nice but after testing on gtmetrix it complained about resized image ; the fact is that they are all resized from 480px × 300px (to 380px × 238px), it means more kb to download for nothing.
    I know it depends on how much photos you like in a row (full width or not) it’s not very effective to declare so many add_image_size in functions.php.
    I ended up with added this to my functions.php

    function wpdocs_remove_then_add_image_sizes() {
    remove_image_size( 'onepress-small' );
    add_image_size( 'onepress-small', 380, 238, true );
}
add_action('init', 'wpdocs_remove_then_add_image_sizes');

    Any thoughts ?

    Hi @marties,

    After adding code in functions.php, do you install & run this plugin to regenerate thumbnail ?

    hi,
    no i used
    wp media regenerate --yes ID_OF_THE_IMAGES
    it is very useful because i only needed to regenerate 10 pictures of all, as i also have another gallery page on the same website which i didn’t need them to be resized.
    But you could as well use regenerate thumbnails plugin.
