New image sizes not shown in standard wp image block

Hi there,

Can you try disabling ALL plugins and see if it appears? Some plugins (usually image optimization plugins) are known to mess with this. It's worth a try.

If it doesn't can you try temporarily changing to a default WordPress theme and check again?

Let us know.

Hi,

Ok so I've just disabled all plugins, the issue was still there

I then switched to Twenty Twenty One theme and that also didn't fix the problem

The new size is not showing in the standard Wordpress image block

Any ideas?

Hi there,

the Image size will only display the sizes available for the image you selected.
If you added the code after images were uploaded you will need to run the Regenerate Thumbnails plugin to create your new custom size.

You can quickly test this by uploading a new image, as WP will automatically create the sizes for new images.

If theres still an issue, then clear any plugin / browser caches

Hi guys,

I did the regenerate again to make sure.

I’ve got all plugins off. No caching. Twenty twenty theme

And still no image size option in standard image box

Im using wp 5.8

Any ideas? Driving me crazy 😜

I’m not a coder do I do struggle with it

I’ve seen this post and it seems I need to add extra code. Additional to the ones you suggest

https://wpmudev.com/blog/wordpress-image-sizes/

What do you think?

This part they say is needed for it to show in the image drop down

<?php

add_filter( 'image_size_names_choose','wpmudev_custom_image_sizes' );

function wpmudev_custom_image_sizes( $sizes ) {
return array_merge( $sizes, array(

//Add your custom sizes here
'custom-image-square' => __( 'Square' ),
'blog-width' => __( 'Blog Content Full Width' ),
) );
}

What do you suggest?

Thanks again for you help 🙏

I would say go ahead and try the code and see if it works for you.

If not then you can mention this to WP's support team and see if they have a suggestion.

GP cannot control the standard image block from WP.

yeah ill give it a try

I was hoping this issue may have arisen before and been resolved already haha

Sounds good :)

Oh, I've figured it out.

I just added the part of the code from wpdev site that shows the options in the drop down.

and change the name of the images to what I use:

<?php

add_filter( 'image_size_names_choose','wpmudev_custom_image_sizes' );

function wpmudev_custom_image_sizes( $sizes ) {
return array_merge( $sizes, array(

//Add your custom sizes here
'custom-image-square' => __( 'Square' ),
'blog-width' => __( 'Blog Content Full Width' ),
) );
}

now the sizes show in the gutenberg image block

:)

Thanks for sharing your solution!
