Thumbnails - by Santhatela - on WordPress WooCommerce support

Investigating further I discovered that:

1) The size 600×600 seems to be being generated by adding in theme-init.php the theme file:

If (! Function_exists (‘etheme_image_sizes’)) {
     Function etheme_image_sizes () {
         Add_image_size (‘shop_catalog_alt’, 600, 600, true);
     }
     Add_action (‘after_setup_theme’, ‘etheme_image_sizes’);
}

But I do not know where this image size is being used ….

2) Size 768 x … is a new size created from version 4.4 of wordpress. It does not appear in the media options, it’s called ‘medium_large’

3) Size 200×300 is created by the YITH plugin WooCommerce Compare (my size… my bad 🙂 ), I think maybe that using the same size of the gallery (140×185) solves the creation of this extra size.

I think maybe using the filter below and regenerating thumbnails again would solve the other images.

/ * Custom filter to remove image sizes thumbnails from WordPress * /
Function remove_default_image_sizes ($ sizes) {

/ * For Default WordPress * /
Unset ($ sizes [‘medium’]); // Remove Medium resolution (300 x 300 max height 300px)
Unset ($ sizes [‘medium_large’]); // Remove Medium Large (added in WP 4.4) resolution (768 x 0 infinite height)
Unset ($ sizes [‘large’]); // Remove Large resolution (1024 x 1024 max height 1024px)

/ * For WooCommerce * /
Unset ($ sizes [‘shop_catalog_alt’]); // Shop Theme thumbnail (600 x 600)

Return $ sizes;
}
Add_filter (‘intermediate_image_sizes_advanced’, ‘remove_default_image_sizes’);

Hi Olga you guys are the best ever.

Wordpress really create mountains of images almost every time we will never use them.

I use a cloud server and I only have 4GB on disk and this becomes a big problem.

The above code did not work so I found a better code and the result was the reduction of about 10 thumbnails for each image to only 4 reducing the disk usage by about 50%

I used:

/* Custom filter to remove image sizes thumbnails from WordPress */
function paulund_remove_default_image_sizes( $sizes) {
unset( $sizes[‘medium_large’]);
unset( $sizes[‘medium’]);
unset( $sizes[‘large’]);
unset( $sizes[‘shop_catalog_alt’]);
return $sizes;
}
add_filter(‘intermediate_image_sizes_advanced’, ‘paulund_remove_default_image_sizes’);

With the optimization of the images and some simple tricks (always trying not to use new plugins) I was able to reach 91 score on GTmetrix, even though it was my store with relatively large images.

Thanks for all and keep pushing
