Found the references but I still don't get.

I click albums on the Space's submenu - that brings up slider of the images - click on an image https://www.wildandrunningfree.com/page/view-album-media?id=55  - 

Now on this page I want to add a block for Posted In - just like the block Posted In for the view Album page.

https://www.wildandrunningfree.com/page/view-album?id=7  (Album > View Image).  

The block on the View Album Page has this code

array (

  'module' => 'bx_albums',

  'method' => 'entity_context',

So I tried this and various permutations - but no luck.

array (

  'module' => 'bx_albums',

  'method' => 'entity_context',

  'params' =>

  array (

    0 => '{profile_id}',

    1 =>

    array (

       'empty_message' => true,

    ),

  ),

Documentation has this

I also see a reference to profile_id and content_id (it that is the way it is written)

It is a single image - no pagination . - only code reference to pagenation is 

'per_page' => 'bx_albums_per_page_profile',

Not for sure about unit_view - 

Any advice because I am lost.
