i added in my functions.php an extra filesize for the thumbs of the sidebar: add_image_size( 'sidebar-thumb', 60, 9999 );
with the add_filter( 'image_size_names_choose', 'my_custom_sizes' ); i could also add them to my media editor.
can you also add them to the widget selection?
or, maybe even better, allow to enter custom size (as 60px x 60px).
i think most people will need here an additional size that is not covered by thumbnail, medium, large, full
thank you very much
