When i remove an image size the generated srcset images are not deleted

When i remove an image size from the configuration and regenerate the media Timmy removes the resized images but keeps the generated srcset images. This results in a lot of unused images in the case of changing image sizes.

Is this intended behaviour?

@jeroenbraspenning No, it’s not intended. When you run Regenerate Thumbnails, it should delete all generated sizes. To investigate further, could you give me some more information?

• Which WordPress version do you use?
• Which Timmy version do you use?
• Can you post the configuration for the image size you deleted?

Thanks for your quick reply!

Wordpress version: Version 5.1.1
Timmy version: 0.14.0
Configuration:

// reset thumbs sizes
set_post_thumbnail_size( 0, 0 );
add_image_size( 'thumbnail', 0, 0 );
add_image_size( 'medium', 0, 0 );
add_image_size( 'medium_large', 0, 0 );
add_image_size( 'large', 0, 0 );

// set sizes
add_filter( 'timmy/sizes', function( $sizes ) {
 
    return array(
        'thumbnail' => array(
            'resize' => array( 150, 150, 'center' ),
            'name' => 'thumbnail',
            'srcset' => array(2),
            'post_types' => array( 'all' )
        ),
    );
} );


// force all image sizes to be generated upon uploading
add_filter('timmy/generate_srcset_sizes', '__return_true');

When i run regenerate image sizes with the above configuration it generates a 150px and 300px version nicely. When i remove the configuration and run regenerate again the 150px versions are removed but the 300px versions remain.

@gchtr This seems to be fixed in v1.0.
On the other hand I noticed, that when I delete an Image in the Media Tab, the generated srcset images remain in the uploads folder. wp media regenerate does not remove them.
