Odd Image Thumbnail Sizes Generated by XStore

Hello @Enduratex,

Thank you for reaching out to us.

The generation of micro-size thumbnails such as 1×1.jpg and 10×5.jpg may be related to theme or plugin functionalities, such as placeholders or lazy loading features. These sizes are not standard WordPress defaults and are likely being created by a custom function or third-party integration.

Regarding the additional thumbnail sizes like 100×100 and 300×300, these are often registered by the WordPress to support various layout and display options. However, if you are certain that these sizes are not required for your website, it is possible to disable them.

To prevent the generation of unwanted image sizes, you can add the following code to your child theme’s functions.php file:

function remove_default_image_sizes($sizes) {
    unset($sizes['thumbnail']); // 150x150
    unset($sizes['medium']);    // 300x300
    unset($sizes['medium_large']); // 768x0
    unset($sizes['large']);     // 1024x1024
    unset($sizes['100x100']);   // Custom size, if registered
    unset($sizes['300x300']);   // Custom size, if registered
    return $sizes;
}
add_filter('intermediate_image_sizes_advanced', 'remove_default_image_sizes');

function remove_custom_image_sizes() {
    remove_image_size('100x100');
    remove_image_size('300x300');
    remove_image_size('1x1');
    remove_image_size('10x5');
}
add_action('init', 'remove_custom_image_sizes');

Please note that this will only prevent new uploads from generating these sizes. Existing images will still retain their previously generated thumbnails unless manually removed.

We also recommend checking your active plugins and theme settings to ensure no additional image sizes are being registered elsewhere.

If you need further assistance or would like us to review your setup in more detail, feel free to provide temporary access or additional information.
