Added unwanted thumbnails #2

Hello @skalanter,

I never needed a plugin for this… did you see the previous discussion please?
► https://wordpress.org/support/topic/latest-version-adds-new-thumbnails/

As explained in the previous thread, I myself annihilate the creation of thumbnails via the functions.php file in my child theme, example:

unset($sizes[‘thumbnail’]);
unset($sizes[‘medium’]);
unset($sizes[‘medium_large’]);
unset($sizes[‘large’]);
unset($sizes[‘woocommerce_thumbnail’]);
unset($sizes[‘woocommerce_gallery_thumbnail’]);
unset($sizes[‘woocommerce_single’]);
Etc…

And it worked fine before version 3. As of version 3, the thumbnails still reappeared and I reported it. You then gave me this :

function remove_extra_image_sizes() {
foreach (get_intermediate_image_sizes() as $size){
if (in_array( $size, array(‘ocean-thumb-m’, ‘ocean-thumb-ml’, ‘ocean-thumb-l’))) { remove_image_size( $size );
}}}
add_action(‘init’, ‘remove_extra_image_sizes’);

Even though I didn’t understand why this was necessary, it worked. But since the last version, the 100×100 thumbnails have reappeared, and without me touching anything.

Finally, I tried to add this to your code: “ocean-thumb”.

This gives :

function remove_thunbails_sizes() {
foreach (get_intermediate_image_sizes() as $size){
if(in_array( $size, array(‘ocean-thumb‘, ‘ocean-thumb-m’, ‘ocean-thumb-ml’, ‘ocean-thumb-l’))) { remove_image_size( $size ); }
}}
add_action(‘init’, ‘remove_thunbails_sizes’);

And there, perfect, no more 100×100 thumbnails.

But it’s not normal to have to add this when the thumbnail removal function is effective in functions.php. Why does your theme refuse to take into account the WordPress original functions?

The code below works perfectly elsewhere, under all themes, without any specific addition:

add_filter(‘intermediate_image_sizes_advanced’, function($sizes){
unset($sizes[‘thumbnail’]);
unset($sizes[‘medium’]);
unset($sizes[‘medium_large’]);
unset($sizes[‘large’]);
unset($sizes[‘shop_catalog’]);
unset($sizes[‘shop_single’]);
unset($sizes[‘shop_single_small_thumbnail’]);
unset($sizes[‘shop_thumbnail’]);
unset($sizes[‘woocommerce_thumbnail’]);
unset($sizes[‘woocommerce_gallery_thumbnail’]);
unset($sizes[‘woocommerce_single’]);
unset($sizes[‘1536×1536’]);
unset($sizes[‘2048×2048’]);
unset($sizes[‘blog-isotope’]);
unset($sizes[‘product_small_thumbnail’]);
return $sizes; });

Since OceanWP v3, I have to add your hook to stop thumbnails creation.
Why ?

Hello @skalanter,

Thank you very much for all these explanations. I will try to look this weekend at what you propose but one thing is sure:

1/ Having checked everything at the time, I promise that I don’t have any other plugin that defines a 100×100 size. Not even me, on the contrary.

2/ I set the Thumbnail Width part to zero. Just like in the WordPress settings, the sizes are zero. Please, see this screenshot: https://postimg.cc/1fB11r82

As I said before, in my functions.php :

add_filter(‘intermediate_image_sizes_advanced’, function($sizes){
unset($sizes[‘thumbnail’]);
unset($sizes[‘medium’]);
unset($sizes[‘medium_large’]);
unset($sizes[‘large’]);
unset($sizes[‘shop_catalog’]);
unset($sizes[‘shop_single’]);
unset($sizes[‘shop_single_small_thumbnail’]);
unset($sizes[‘shop_thumbnail’]);
unset($sizes[‘woocommerce_thumbnail’]);
unset($sizes[‘woocommerce_gallery_thumbnail’]);
unset($sizes[‘woocommerce_single’]);
unset($sizes[‘1536×1536’]);
unset($sizes[‘2048×2048’]);
unset($sizes[‘blog-isotope’]);
unset($sizes[‘product_small_thumbnail’]);
return $sizes; });

If I test all this with another theme, no thumbnails.
If I put OceanWp back in, the thumbnails still appear.

So I have to add this to make them disappear again:

function remove_extra_image_sizes() {
foreach (get_intermediate_image_sizes() as $size){
if (in_array( $size, array(‘ocean-thumb-m’, ‘ocean-thumb-ml’, ‘ocean-thumb-l’))) { remove_image_size( $size );
}}}
add_action(‘init’, ‘remove_extra_image_sizes’);

Anyway, I’ll test various things but it’s pretty mathematical in the end, because if another plugin added the 100×100 size, the other themes would be forced to do it too.

I’ll come back to you if I find something else…
Thanks anyway, I really appreciate your availability 😉
