Able to see a variable in print_r()'s output, but not sure how to access it in code

I googled, installed Devel, Drupal for Firebug, but I can't find it.

I found what I want, I know where it is; I just don't know how to get it.

I'll put this in code brackets, but Devel tells me the file name (which I want to stick into the .tpl.php file) is here:

field_image (Object) stdClass 
  handler (Object) views_handler_field_field 
    view (Object) view 
      result (Array, 2 elements) 
        0 (Object) stdClass 
          _field_data (Array, 1 element) 
            nid (Array, 2 elements) 
              entity (Object) stdClass
                field_image (Array, 1 element) 
                  und (Array, 1 element)
                    0 (Array, 11 elements)                                      
                      filename (String, 23 characters ) FILENAME.jpg

So, how do I get that FILENAME.jpg to be output using PHP?

<?php print $something->other; ?>
