Why $image[$cache_key] = $image? Warning appears

    The line

    148 $image[$cache_key] = $image;

    throws a warning in the WordPress backend in the Favourite Image column:

    “Warning: Illegal string offset ‘featured_column_thumbnail’ in /www/htdocs/root/wp-content/plugins/featured-image-column/featured-image-column.php on line 148”

    The warning disappears if the above mentioned line is commented out or deleted.

    What is the purpose of this line?
