 * Fallback image doesn’t work for posts-block or cover template. Actually, I can’t
   see where it works, but those are the places I looked. 🙂

 * Hi Johan,
 * The fallback image is mostly used in preview.php (on archive pages) and in the
   recent posts widget. It’s not used for the main image on singular pages, since
   I thought most people wouldn’t want to display a fallback image in that space.
 * I didn’t think it was possible to filter the image output in the block editor
   content, but it turns out it is, so the posts block will get support for the 
   fallback images in the next version of Chaplin.

 * Hi [@jonkastonka](https://wordpress.org/support/users/jonkastonka/),
 * This was added not long after I posted, and it’s working (for the posts block)
   for me when running the latest version of Chaplin and WordPress. I didn’t add
   it for the cover block.

 * I’m using the posts block as well but it’s not working. Or am I misunderstanding
   how it’s supposed to work.

 * Ah. The fallback image only shows up in the Latest Posts block for posts other
   than the current one, since the conditionals try to prevent the fallback from
   being used for the main entry image area. I’ve updated the conditionals in version
   2.6.7 to make sure that the fallback shows up for the current post as well.

 * Ok, it works on native block “Latest Posts” but not on the block “Posts” from
   CoBlocks, which is the one I’m using. Maybe that isn’t possible to hook on to
   from a theme level.

 * [@jonkastonka](https://wordpress.org/support/users/jonkastonka/) Yeah, it’s entirely
   possible that the CoBlocks block doesn’t use `has_post_thumbnail()` and the `
   post_thumbnail_html` filter, so there’s no way to filter the result before it’s
   output.
