# Update ‘Default’ Block Style

 * I am trying to programmatically update the default block style of an image block.
 * When a user updates a custom select dropdown in the editor (using ACF plugin),
   I trigger a JS function that unregisters the default core/image style, and registers
   a new one, setting it to the default style.
 * e.g
 *     ```
       wp.blocks.unregisterBlockStyle(
         'core/image',
         [ 'retailResidential', 'weddingsEvents', 'advertisingEditorial']
       );
   
       wp.blocks.registerBlockStyle( 'core/image', {
         name: "weddingsEvents",
         label: "weddingsEvents",
         isDefault: true
       });
       ```
   
 * Then when a user creates a new image block, I want the updated image style class(
   which should be the default), to be automatically applied to the image.
 * However, this is not working, and I am unable to programmatically update the 
   default style in this way. If I manually update the default style using the ‘
   Default Style’ select/dropdown it seems to work for adding additional images,
   but can not do this with JS.
 * Any help is greatly appreciated. Thank you for reading.

   They really do want to understand the challenges people are facing when trying
   to extend the editor.
